| 摘 要： | 本文研究了高温轻介质中辐射流体力学的一种近似——等温近似.在这种近似中,突出地强调了辐射热传导的作用,即认为介质中的温度分布由于热传导极强而可以近似地看成与空间无关.在讨论了这种近似的适用条件后,分别用它就一维流的情况研究了连续流、稀疏波和压缩波以及激波等运动形态.

| Abstract: | A kind of approximation to radiation-hydrodynamics in high temperature light media, isothermal approximation, is studied. In this approximation, it is assumed that the effect of radiative heat transfer would be so strong that the temperature of the medium could be regarded as uniform. After discuss- ing the conditions under which this approximation could be used, it is applied to study various 1-dimensional flows: continuous flows, rarefaction, compression waves and shock waves. |
