A two-dimensional transient model for convective heat transfer and surface tension driven fluid flow is developed. The model describes the transient behavior of the heat transfer process of a stationary band source. Some semi-quantitative understanding of scanning is obtained by a co-ordinate transformation. The non-dimensional form of the the equations are derived and four dimensionless parameters are identified, namely, Peclet number (Pe), Prandtl number (Pr), Surface tension number (S), and dimensionless melting temperature. Their governing characteristics and their effect on pool shape, cooling rate, velocity field and solute redistribution is discussed. Numerical solution is obtained and presented.
