移动热源法在冰水相变过程中的数值计算
Numerical Calculations of Phase Change about Ice and Water Using Moving Heat Source Method
采用移动热源法,数值模拟求解冰水相变传热过程。在一维半无限大空间内的双相区域问题中,通过导热方程源项的线性离散和数值计算,获得冰水区域内的温度分布,并且将数值解同精确解进行比较,从结果中可以看出两者的一致性。这些充分证明了本文数值分析的可行性,也为它在工业界的应用提供有益的参考。
he problem of phase change about ice and water was solved in the structured meshes by using moving heat source method, which is representative of many industrial processes. The temperature field was also studied by discrete source term. A bilateral regions problem was given to demonstrate the correctness of this method; the results are agreement when the numerical solution was compared with the exact solution. These demonstrate feasibility of the numerical calculation fully, as well as its application in industry to provide useful information.
