The boundary conditions are that there is no slip on the surface, and that the temp and velocity relax to 0 far away and that the temperature on the surface is fixed
The are in terms of the newest notation:
η = 0, f = f' = 0, T* = 1,
η->∞, f' = 0, T* = 0.
Note that f is the normal velocity, f' is the tangential velocity and T* =
, where T0 is the far away temperature.
