This fact is not documented by the majority of CFD brokers. Criticism has also been expressed about the way that some CFD providers hedge their own exposure and the conflict of interest that this could cause when they define the terms under which the CFD is traded.

One article suggested that some CFD providers had been running positions against their clients based on client profiles, in the expectation that those clients would lose, and that this created a conflict of interest for the providers.

CFDs, when offered by providers under the market maker model, have been compared [25] to the bets sold by bucket shops , which flourished in the United States at the turn of the 20th century.

These allowed speculators to place highly leveraged bets on stocks generally not backed or hedged by actual trades on an exchange, so the speculator was in effect betting against the house.

Bucket shops, colourfully described in Jesse Livermore 's semi-autobiographical Reminiscences of a Stock Operator , are illegal in the United States according to criminal as well as securities law.

In addition, for this type of flow, the next discussion highlights the hierarchy of flow equations solved with CFD.

Note that some of the following equations could be derived in more than one way. The stability of the selected discretisation is generally established numerically rather than analytically as with simple linear problems.

Special care must also be taken to ensure that the discretisation handles discontinuous solutions gracefully.

The Euler equations and Navier—Stokes equations both admit shocks, and contact surfaces. The finite volume method FVM is a common approach used in CFD codes, as it has an advantage in memory usage and solution speed, especially for large problems, high Reynolds number turbulent flows, and source term dominated flows like combustion.

In the finite volume method, the governing partial differential equations typically the Navier-Stokes equations, the mass and energy conservation equations, and the turbulence equations are recast in a conservative form, and then solved over discrete control volumes.

This discretization guarantees the conservation of fluxes through a particular control volume. The finite volume equation yields governing equations in the form,.

The finite element method FEM is used in structural analysis of solids, but is also applicable to fluids.

However, the FEM formulation requires special care to ensure a conservative solution. The FEM formulation has been adapted for use with fluid dynamics governing equations.

The finite difference method FDM has historical importance [ citation needed ] and is simple to program. It is currently only used in few specialized codes, which handle complex geometry with high accuracy and efficiency by using embedded boundaries or overlapping grids with the solution interpolated across each grid.

Spectral element method is a finite element type method. It requires the mathematical problem the partial differential equation to be cast in a weak formulation.

This is typically done by multiplying the differential equation by an arbitrary test function and integrating over the whole domain.

Purely mathematically, the test functions are completely arbitrary - they belong to an infinite-dimensional function space.

Clearly an infinite-dimensional function space cannot be represented on a discrete spectral element mesh; this is where the spectral element discretization begins.

The most crucial thing is the choice of interpolating and testing functions. In a spectral element method however, the interpolating and test functions are chosen to be polynomials of a very high order typically e.

This guarantees the rapid convergence of the method. Furthermore, very efficient integration procedures must be used, since the number of integrations to be performed in numerical codes is big.

Thus, high order Gauss integration quadratures are employed, since they achieve the highest accuracy with the smallest number of computations to be carried out.

At the time there are some academic CFD codes based on the spectral element method and some more are currently under development, since the new time-stepping schemes arise in the scientific world.

In the boundary element method, the boundary occupied by the fluid is divided into a surface mesh. High-resolution schemes are used where shocks or discontinuities are present.

Capturing sharp changes in the solution requires the use of second or higher-order numerical schemes that do not introduce spurious oscillations.

This usually necessitates the application of flux limiters to ensure that the solution is total variation diminishing.

In computational modeling of turbulent flows, one common objective is to obtain a model that can predict quantities of interest, such as fluid velocity, for use in engineering designs of the system being modeled.

For turbulent flows, the range of length scales and complexity of phenomena involved in turbulence make most modeling approaches prohibitively expensive; the resolution required to resolve all scales involved in turbulence is beyond what is computationally possible.

The primary approach in such cases is to create numerical models to approximate unresolved phenomena. This section lists some commonly used computational models for turbulent flows.

Turbulence models can be classified based on computational expense, which corresponds to the range of scales that are modeled versus resolved the more turbulent scales that are resolved, the finer the resolution of the simulation, and therefore the higher the computational cost.

If a majority or all of the turbulent scales are not modeled, the computational cost is very low, but the tradeoff comes in the form of decreased accuracy.

In addition to the wide range of length and time scales and the associated computational cost, the governing equations of fluid dynamics contain a non-linear convection term and a non-linear and non-local pressure gradient term.

These nonlinear equations must be solved numerically with the appropriate boundary and initial conditions. An ensemble version of the governing equations is solved, which introduces new apparent stresses known as Reynolds stresses.

This adds a second order tensor of unknowns for which various models can provide different levels of closure.

It is a common misconception that the RANS equations do not apply to flows with a time-varying mean flow because these equations are 'time-averaged'.

In fact, statistically unsteady or non-stationary flows can equally be treated. There is nothing inherent in Reynolds averaging to preclude this, but the turbulence models used to close the equations are valid only as long as the time over which these changes in the mean occur is large compared to the time scales of the turbulent motion containing most of the energy.

Large eddy simulation LES is a technique in which the smallest scales of the flow are removed through a filtering operation, and their effect modeled using subgrid scale models.

This allows the largest and most important scales of the turbulence to be resolved, while greatly reducing the computational cost incurred by the smallest scales.

Regions near solid boundaries and where the turbulent length scale is less than the maximum grid dimension are assigned the RANS mode of solution.

As the turbulent length scale exceeds the grid dimension, the regions are solved using the LES mode. Therefore, the grid resolution for DES is not as demanding as pure LES, thereby considerably cutting down the cost of the computation.

Direct numerical simulation DNS resolves the entire range of turbulent length scales. This marginalizes the effect of models, but is extremely expensive.

The coherent vortex simulation approach decomposes the turbulent flow field into a coherent part, consisting of organized vortical motion, and the incoherent part, which is the random background flow.

The approach has much in common with LES, since it uses decomposition and resolves only the filtered portion, but different in that it does not use a linear, low-pass filter.

Instead, the filtering operation is based on wavelets, and the filter can be adapted as the flow field evolves. Goldstein and Vasilyev [59] applied the FDV model to large eddy simulation, but did not assume that the wavelet filter completely eliminated all coherent motions from the subfilter scales.

This approach is analogous to the kinetic theory of gases, in which the macroscopic properties of a gas are described by a large number of particles.

PDF methods are unique in that they can be applied in the framework of a number of different turbulence models; the main differences occur in the form of the PDF transport equation.

The PDF is commonly tracked by using Lagrangian particle methods; when combined with large eddy simulation, this leads to a Langevin equation for subfilter particle evolution.

The vortex method is a grid-free technique for the simulation of turbulent flows. It uses vortices as the computational elements, mimicking the physical structures in turbulence.

Vortex methods were developed as a grid-free methodology that would not be limited by the fundamental smoothing effects associated with grid-based methods.

To be practical, however, vortex methods require means for rapidly computing velocities from the vortex elements — in other words they require the solution to a particular form of the N-body problem in which the motion of N objects is tied to their mutual influences.

A breakthrough came in the late s with the development of the fast multipole method FMM , an algorithm by V.

Rokhlin Yale and L. Greengard Courant Institute. This breakthrough paved the way to practical computation of the velocities from the vortex elements and is the basis of successful algorithms.

They are especially well-suited to simulating filamentary motion, such as wisps of smoke, in real-time simulations such as video games, because of the fine detail achieved using minimal computation.

Software based on the vortex method offer a new means for solving tough fluid dynamics problems with minimal user intervention. Among the significant advantages of this modern technology;.

The vorticity confinement VC method is an Eulerian technique used in the simulation of turbulent wakes. It uses a solitary-wave like approach to produce a stable solution with no numerical spreading.

VC can capture the small-scale features to within as few as 2 grid cells. Within these features, a nonlinear difference equation is solved as opposed to the finite difference equation.
