轴对称椭球体移动过程的接触熔化研究

Study on the Contact Melting around a Migrating Axial Symmetry Ellipsoid

研究了相变材料围绕移动的轴对称椭球体热源的接触熔化．得到熔化速度、熔化体积与热源表面温度的分析解．讨论了椭圆压缩比对这些特征参数的影响，并与相同体积的球体热源的接触熔化过程进行了比较，得到一些有益的结果．当压缩比为１时，有关结果将适用于圆球．

The contact melting of phase change material around a migrating symmetry ellipsoid heat source is analysed. The theoretical formulas of axial melting velocity and surface temperature of the heat source, melt solid volume are obtained. The effect of compression ratio on these parameters is discussed. Some useful conclusions are drawn. The results provide an important base for the geological prospecting and nuclear waste self burial process, including those of the melting around the spherical heat source.
