Projection method: B.C. for intermediate velocity field

pranavladkat · August 11, 2014, 13:00

Hello,

I'm trying to solve the variable density and viscosity Navier-Stokes using lagged-pressure projection method on a collocated grid.

What is the boundary condition on the intermediate velocity field (U*) that we obtain which not divergence free?

I see a lot of confusion about correct B.C. in the literature also I could not find good source which specifies the correct source of B.C. If anyone can point me to correct literature, that would be great help.

Thank you
