Estimating computer resources for LBM - multiphase, chemically reacting, turbulent

Hello folks,

I’m relatively new to this technique and to intensive computation. Could you point me to any resources that would help me to estimate the computer resources needed for LBM problems, such as jet in cross flows and multiphase reacting flows?

How would these needs compare with the continuum-based LES?

The domain is about tens of centimeters.

Thanks for your help!
