- Solution_algorithms_for_pressure-velocity_coupling_in_steady_flows abstract "Solution algorithms for pressure-velocity coupling in steady flows are the standard prepossessing methods used to solve steady flow problems in computational fluid dynamics.The convection of the scalar variable Φ used to define fluid flow depends on the magnitude and direction of the local velocity field. In general, however the velocity field is not known. These algorithms are hence employed to obtain the solution.The standard momentum and continuity equations can be given by:The momentum equationsObtained by substituting Φ with standard directional vectors of the velocity field u, v, and w. The continuity equation where is the density, u, v, are the x- and y-directional components of velocity, p is the pressure field and Su,v are the source terms.These equations are however hard to solve due to non-linearity in the momentum equations and interdependence of the pressure term in all three equations. Also, for a general purpose flow equation, the pressure field is also unknown and is to be solved for as well.If the flow field is compressible, the above equations act as the standard temperature and density equations and pressure can be found as it is a function of them both.If, however the flow is in-compressible, the pressure is independent of density. Hence, coupling is necessary to induce a constraint on the solution. The resulting fields will then satisfy the continuity equations. Both these issues are solved via the application of the SIMPLE Algorithm and its derivatives.For general purpose and definition of these algorithms, a Staggered CFD Grid shall be used. It ensures the presence of very real non-zero pressure gradient across the nodes in any condition, even in the case of a checkered grid. The staggering also ensures realistic behaviors of the descretized momentum equations for spatially oscillating pressures.Also, the direction of the velocity vectors are exact.".
