 January 7, 2001, 22:40 ADI of N-S equations #1 Zhou Yongcheng Guest   Posts: n/a Dear all: Could anyone tell me how to deal with nolinear terms in N-S equations with ADI method and the pressure terms? Thanks in advance. Zhou Yongcheng

 January 8, 2001, 20:02 Re: ADI of N-S equations #2 John C. Chien Guest   Posts: n/a (1). The book by Anderson, Tannehill and Pletcher, "Computational Fluid Mechanics and Heat Transfer" has a chapter on numerical method of Navier-Stokes, which includes ADI related schemes. (2). You can read the text and find the reference materials.

For 3D N-S equations you better go for LU Approximations(example: LU-SGS by A.Jameson). 1)We will treat Non-linear viscous terms explicitly. 2)pressure term will be expressed in terms of u,v,w,rho and e.

Flat front simulation. The solution is derived using the modulator function as discussed in my abstract. It clearly shows the mitigation of both diffusion and dispersion errors. I can't say enough about ADI. It is an excellent adaptable method, having even used it in phase change heat transfer simulations. regards Dean
