Numerical simulation of fluid flow and heat transfer with a moving heat source

In the present study, using a fixed-grid source-based method, a three-dimensional numerical model for a convection–diffusion phase change process. A simulation has performed by FLUENT for the detailed prediction of heat transfer, phase change and fluid flow in welding process with moving heat source. During laser melting has been studied the problem is formulated by considering the three-dimensional equations of continuity, momentum and energy based on enthalpy model. The equation is solved using a fully implicit, control-volume-based computational method for fixed grids. The numerical results show good compatibilities with previous investigations.
