【Abstract】 In this paper, the simulation code of the REFLOW is developed for non-isothermal,fluid flow of filling the variable thickness cavity.The modeling is based on a finite-element/finite-difference formulation for inelastic, non-Nuton fluid under condition of Hele-Shaw flow. The simulation results are in good agreement with the experimental ones.更多还原
