FD NS implicit solver

i am a research scholar in iit madras.i am in need of a finite difference navier-stokes implicit solver.either you provide me the solver or give me the guidelines for developing it.also guide me how to generalise the boundary conditions.

(1). Let us know the answer, if you have found one.

Re: FD NS implicit solver

I just succesfully developed the solver of Navier-Stokes momentum equation by finite-difference method. I applied the implicit scheme by utilization of SIMPLE algorithm that had developed by Patankar [Numerical Heat Transfer and Fluid Flow by Patankar, S.V., 1980, Hemisphere Pub.]. I applied the staggered grid to solve this problem to avoid zigzag pressure on it.

Beside this method, you can use the finite volume method that clearly developed by Patankar (1980). It's similarly. Please, to contact me if you have a problem about it.

Thanks

Re: FD NS implicit solver ?

What a bout results given by your solver of Navier-Stokes momentum equation by finite-difference method ?

Re: FD NS implicit solver ?

I developed a source code to get a simulation about the streamline of 2D-velocity in cylindrical column of empty or filled by packed bed. This code utilize the algorithm of SIMPLE that developed by Patankar (1980). So, we can give the contour of pressure distribution in the domain. I had applied this system on a deep bed dryer simulation. Thanks

Re: FD NS implicit solver ?

how did you take care of the velocity profiles inside the bed..i presumen its a porous bed..?
