轴对称有无相变导热问题的双倒易边界元模拟

Simulation of Axisymmetric Heat Conduction with and without Phase change by Dual Reciprocity Boundary Element Method

发展了轴对称问题的双倒易边界元方法 .引入一个新的f函数 ,解决了以前使用的f函数在对称轴上存在奇异性的问题 。

An elaborate dual reciprocity boundary element formulation for axisymmetric problems has been derived. A new function f was proposed to eliminate the singularity on symmetric axis in the original function f used in published papers. The new function f was successfully used to calculate some transient heat conduction and moving boundary condition with phase change.
