采用有限差分法数值求解了强非线性二维相变传热三区问题——沥青加热熔化问题．模拟计算中考虑了沥青的变物性及液相区的自然对流，对Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程的解采用了ω－ψ法，计算结果为筑路沥青热加工技术方法的改进提供了一定的理论依据
The finite difference method is used to numerically solve the three-zone problem of strong nonlinear two-dimensional phase transition heat transfer - asphalt heating and melting problem. Taking into account the physical properties of asphalts and the natural convection in the liquid zone, the ω-ψ method is applied to the solution of the Navier-Stokes equations. The calculation results provide a theoretical basis for the improvement of technical methods of hot asphalt processing
