Abstract

An approximate analytical solution of the problem of melting and evaporation during disruptions in magnetic fusion reactors is developed via a technique known as the heat balance integral method. The heat balance integral method has been used successfully in the past in analyzing a variety of heat transfer problems, and is particularly well suited to handle nonlinear boundary value problems such as the one considered in this paper. The results obtained with this approach are then compared with results generated via a numerical techniques based computer code developed elsewhere. It is found that the results obtained via this method are quite reasonable in view of the assumptions made in developing the solution. In addition, some tentative approximate scaling laws are derived.

磁聚变反应堆中断过程中熔化和蒸发问题的近似解析解

利用热平衡积分法，给出了磁聚变反应堆中断过程中熔化和蒸发问题的近似解析解。热平衡积分法已成功地用于分析各种传热问题，特别适合于处理非线性边值问题，如本文所考虑的问题。用这种方法得到的结果，然后与其他地方开发的基于计算机代码的数值技术产生的结果进行比较。考虑到在求解过程中所作的假设，用这种方法得到的结果是相当合理的。此外，还推导了一些近似的试探性标度定律。
