Is it possible to use exact difference method for original Shan Chen LBM?

02 March 2019 1 8K Report

Is EDM scheme can improve original SC method without implementation of equation of States as described by Yuan Schaefer?

Ernesto Monaco

Dear Debashis,

yes, it is possible. The stability increase does not depend on the Equation of State, but on the viscosity. Actually, it is even not limited to multiphase/multicomponent problems, as it is a model to incorporate a generic body force (which could be for instance gravity, or the force used to mimic a pressure gradient in a Poiseuille flow with periodic inflow/outflow).

Best Regards,

Ernesto
