Boundary element analysis ofl-D unsteady convective-diffusion equation with radiant heat flux and phase change moving interface W.-Q. Lu Department of Physics, Division of Thermal Science, Graduate School, Chinese Academy of Sciences, P.O. Box 3908, Beijing 100039, China ABSTRACT A boundary element method for solving ID transient convective-diffusion equation with radiant heat flux and phase change moving interface is developed and used to analyze the frozen process in CPL condenser. INTRODUCTION The numerical simulation of two-phase free surface and moving interface prob- lems is the frontier and hot spots in numerical computation. Boundary element method(BEM) has provided potential advantages of storage and computational requirements over finite difference method and finite element method. Moreover, the discretization of free surface and moving interface can be directly made in BEM, therefore BEM is very suited to the modelling of this class of problems^'*'. Transi
