happy new year hope you all have a beautiful year ahead.
i work on multicomponent Shan-chen. i have little problem with velocity in shan-chen multicomponent.
As you know each component has two density.(main density and dissolve density or no fluid). I think velocity of main component is correct but velocity of dissolve density is very high .for example for Poiseuille flow, velocity of main component(rho=2) is 0.000075 but velocity of other component( dissolve density rho=0.06) in same point is 0.0017 .also when i simulate a drop in periodic box, velocity of dissolve density is very higher than velocity of main density , do you think my code is incorrect and It has a bug? My density is good in each component but velocity of dissolve density is much than velocity in main density. I really confused . can you help me ? How I can fix this bug?
I use lb2d-prime-dev for my work . do you think lb2d-prime-dev has a bug and problem in calculation velocity in dissolve density?
