摘要
Lin-Reissner-Tsien方程描述了在跨音速近似下的不稳定跨音速流动.通过相似变换,将Lin-Reissner-Tsien方程简化为一个常微分方程.然后解析求解所得到的方程,并在某些情况下得到的正好是精确解.上述情况下无法得到精确解时,给出了数值模拟.还得到了行波解.
The Lin-Reissner-Tsien equation describes unsteady transonic flows under the tran- sonic approximation. The equation was reduced to an ordinary differential equation via a simi- laxity transformation. The resulting equation was then solved analytically, and in some cases even exactly. Numerical simulations were provided for the cases in which there were no exact solutions. Traveling wave solutions were also obtained.
