Abstract: In this paper, the boundary layer function method, an effective method for the solution of singular perturbation, was presented and used to deal with the heat transfer in thin rectangular plates.

Key words: singular perturbation, boundary layer, lengthening variable, angular point, boundary layer function, angular boundary layer function, boundary layer variable
