摘要
考虑了欧拉坐标下一维黏性辐射流体系统的初始边界值问题,利用能量方法和一些基本不等式来估计解在H4空间中的整体存在性。在这里假设热传导系数的增长指数是非负常数,特别是热传导系数是常数也是成立的。
It was concerned with the initial-boundary problem of 1 -D radiative and reactive viscous gas dynamics under Euler coordinate. The global existence of the solution in space H4 is estimated by using the energy method and some basic inequalities. Assuming that the growth exponent of heat conductivity is allowed to be any nonnegative constant, in particular, constant heat conductivity is allowed.
