wall heat flux
 

how can i implement constant wall heat flux boundary condition??

Re: wall heat flux
 

This is straightforward in finite volume method. The flux on a wall face will involve only terms containing the wall normal temperature gradient

-k dT/dn

which you can replace with the prescribed flux.

your own program - i mean written by you?

hi guy i'm using (M.PERIC 2D AXISYMMETRIC COLLOCATED GRID,CODE) in this code i have to implement constant flux B.C in source terms e.g qs=su+sp*Tp (Tp temperature of considered node) how can i do this?

sorry for intrupt

if this ur code then make -k dT/dX = Q(const) in fourieers and solve to get CI and PI, resultant eqn will represent such a boundary condition.
