Three different solution methods for the finite-volume discretized incompressible Navier-Stokes equations have been tested: segregated approaches, built around coupling methods such as SIMPLE, SIMPLER and PISO plus a line Gauss-Seidel linear solver; coupled methods, incorporating a penalty formulati

β¦ Synopsis
In many popular solution algorithms for the incompressible Navier-Stokes equations the coupling between the momentum equations is neglected when the linearized momentum equations are solved to update the velocities. This is known to lead to poor convergence in highly swirling flows when coupling between the radial and tangential momentum equations is strong. Here we propose a coupled solution algorithm in which the linearized momentum and continuity equations are solved simultaneously. Comparisons betwem the new method and the well-known SIMPLEC method are presented.

We compare the performance of different pressure correction algorithms used as basic solvers in a multigrid method for the solution of the incompressible NavierΒ±Stokes equations on non-staggered grids. Numerical tests were performed on several cases of lid-driven cavity Β―ow using four different pres
A cellular automata method for the prediction of incompressible fluid flows is presented and its practical relevance is investigated by comparing it with a standard finite volume solver. The cellular automata approach is based on an advanced lattice Boltzmann technique for a discrete microscopic des
A comparison of multigrid methods for solving the incompressible Navier -Stokes equations in three dimensions is presented. The continuous equations are discretised on staggered grids using a second-order monotonic scheme for the convective terms and implemented in defect correction form. The conver
