,Computation of Steady Viscous Flow Near a Ship’s Stern,irst some alternative approaches are reviewed which have emanated from different views on how to deal with the pressure in the primitive variable formulation of the Navier-Stokes equations. Then a particular solution method is described. The underlying mathematical model is a slightly reduced form o

Convection-Diffusion Phenomena and a Navier-Stokes Processor,t of convection-diffusion equations. These equations can numerically be solved using a single algorithm based on the finite domain or control volume method. For turbulent transport a k-ɛ model is often used. This requires that in some cases an experimental validation for a completely new flow situat

Multigrid and Defect Correction for the Efficient Solution of the Steady Euler Equations,rived by considering the laws of conservation of mass, momentum and energy for an inviscid gas. The result is a nonlinear hyperbolic system of conservation laws. Only for very simple flow problems, analytical solutions exist. For almost all engineering problems solutions must be found numerically. S

Weakly-Reflective Boundary Conditions for Shallow Water Equations,n the necessity of this type of boundary conditions the mathematical formulation of the problem is given together with the essential aspects of the derivation. The numerical implementation of these conditions in finite element and finite difference codes is considered and results are given for some

Multigrid and Defect Correction for the Efficient Solution of the Steady Euler Equations,enerally the computational cost is high. In 1983 a project was started at the Centre for Mathematics and Computer Science (CWI) in Amsterdam for the development of more efficient methods. So far, a multigrid method for the solution of the 2D steady Euler equations has been developed, implemented and tested.
