Drag coefficient calculation

Lattice Boltzmann Method LBM: Theory
#1

Dear all

I am a newbie in LB method and I want to calculate drag coefficient of an obstacle using it.
I read some papers and all posts in the forum, But i can not understand algorithm of calculation.

Can anyone help me to find algorithm (or psedu-code) of drag coefficient calculation using momentum exchange method?

Thanks very much

hi smm
prof. mei et al describe clearly in their paper, named:

Renwei Mei, Dazhi Yu, Wei Shyy and Li-Shi Luo, Force evaluation in the lattice Boltzmann method involving curved geometry, Phys. Rev. E 65 (2002), pp. 1/041203–14/041203.

or you can find another in this:

its very clear describe!!

Thank you very much ehsan!

Many of papers in LB don’t explain their methods very well, but this 2 paper are very good.

… pls check your PM.

I have a private question from you ( not about LB! )

cheers
