Hi everybody,
I am solving a heat and fluid flow problem of a porous evaporator in a thermal management device called capillary pumped loop(CPL).I successfully prepared the source terms for the governing continuity,momentum and energy equations of the fluid flowing through the porous wick and the vapor groove.But i am facing problem to give the boundary conditions which are in the form of velocity and temperature gradients(like: at x=0...u=0,dv/dx=0,dw/dy=0,dT/dy=0,e.t.c).
How to give such kind of boundary conditions??They are gradients,so can i use "Gradient(G)vector macros" in my udf.If yes,how?if no,what can i do to give these boundary conditions.Please try to give me solutions soon.

Thanks in advance to all,
Kishore
