Reply To: High density/viscosity ratio Free Energy method
As far as I know, the relaxation time of the hydrodynamics lattice for the fluids with two different viscosities can be accounted using this equation: 1 / tau_f = c_1 / tau_1 + c_2 / tau_2.
Would you please advise how the dynamics can be implemented using variable relaxation time? Is there any specific example that I can look into to learn how to implement this? Thanks.
