Based on momentum theory and shock wave gas dynamic theory , jet equivalent body idea and bow sharp wave mathematic formula is brought forward 利用动量定理和激波理论分析方法,提出了喷流等效体的概念,推导了等效体弓形激波方程。
The simulation of three examples shows that the method has high - resolution when it is applied in unsteady and quasi - steady flows with the sharp wave in discontinuous problems and suitable to computation of the shallow water flows 对二个模型算例的数值模拟结果表明:该算法对拟恒定流和非恒定流模拟都有较高的分辨率,具有处理间断问题的锐利波形能力,适合浅水流动的数值模拟。
