Advection scheme
Hi ! Would you please advise which EXPLICIT scheme is best/good for solving pure advection problems that gurantees the mass conservation? Thanking. Tanaka.

Re: Advection scheme
If you use conservative advection form, then the mass conservation is gurantted.

Re: Advection scheme
Hi Kim thanx for the quick response. I will use conservative form. But please tell the name of the scheme, which is not diffusive, non-oscilllatory and perfectly conserves the mass. Thankx again, Tananka

Re: Advection scheme
ENO or WENO are quite popular these days for the advection scheme. You can look at Chi-Wang Shu's webpage for the references.

Re: Advection scheme
Thank you very much Dr. Kim. Would you kindly email me a copy of the code (fortran or c or c++) for any of the these schemes. I want to incorporate in my 3D code. Tanaka, Japan

Re: Advection scheme
Send your code to me, then I will add the 2nd order ENO or the 5th order WENO advection scheme and send you back. If possible, send related paper for your code for me to better understand your code.

Re: Advection scheme
It seems to me that HLPA scheme by Zhu J. is the best

Re: Advection scheme
Thanx a lot for the input, I will check the article regards, Tanaka

Re: Advection scheme
Dear Tanaka
Unfortunately I have not the article, I myself far away from it. :(( But I found description using Google and here is the link http://www.lkt.iet.ethz.ch/~lakehal/...4/material.htm see chapter 4 Mike |
Re: Advection scheme
to be more exact
at the page you open will be Chapter 1: Introduction to the Course, Navier-Stokes and Heat Convection Equations Chapter 2: Numerical Thermal Analysis I: Finite Difference Method Chapter 3: Numerical Thermal Analysis II: Finite Volume Method Chapter 4: Phenomenology of Turbulence Chapter 5: Turbulence Modelling ----------------------------------------------- - Choose Chapter 3 - there will be Chapter 4 (in pdf) - page 56 |
