N2 - The thermocapillary flow that occurs during laser melting is investigated using an asymptotic method. The molten region is assumed to be a long, rectangular cavity with the side and bottom walls at the melting temperature of the material. The top free surface of the material is subjected to an inhomogeneous heating source. The motion of the fluid is governed by the Navier-Stokes equations coupled with the heat equation. An asymptotic solution, in the limit case of the aspect ratio A yields 0, is found and discussed for the cases where the surface deformation may be neglected.
