comment Heat transfer: boundary conditions with fluid velocity
@mkl314 --- perhaps this discussion (on whether the $v\cdot n$ in the boundary condition should be multiplied by $u$ or by $u-u_b$) can be settled by just considering what would happen if you would open a window in your room; there's a draft ($v\cdot n\neq 0$), but the temperature inside and outside is the same ($u=u_b$). Surely one would not expect a temperature gradient to appear?
