ISOTHERMAL APPROXIMATION TO RADIATIONHYDRODYNAMICS IN HIGH TEMPERATURE LIGHT MEDIA
Huang Zuqia (Institute of Low Energy Nuclear Physics, Beijing Normal University)
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.
