I am trying to solve a heat trasfer problem. In that,I wanted to apply the boundary condition at the wick/vapor interface(considerd as flat boundry) as given in the attachment in eqn (5).can anybody help me in this regard?

Thanks in advance

FYI: This problem has been tackled (assume this question is a copy/paste out of the article). Have a look at "Transport in Flat Heat Pipes at High Heat Fluxes From Multiple Discrete Sources" by Vadakkan, Garimella, and Murthy. Journal of Heat Transfer, June 2004, Vol 126.

The first term in the equation is heat transfer by conduction. There is no conduction, the only heat transfer process from air to the wick is via convection process.
