The numerical simulation technique is used to investigating the isentropic Mach number distribution on the different swept height blade surfaces of a turbine last stage blades.
采用数值模拟技术详细地研究了不同掠高的某蒸汽轮机末级前掠叶片表面等熵马赫数的分布。
The flow field parameter distribution can be affected more in upper stream, especially near the leading edge area while the Mach number distribution of the upstream blade surface is affected little.
对上游进口段,特别是靠近叶片前缘区域流场参数分布有较大影响,但对于上游叶片表面马赫数影响不大。
The distribution of wall temperature is greatly influenced by the fuel supply quantity and the Mach number of main stream, but little influenced by the temperature of main stream.
供油量和主流马赫数对试验件的壁温分布趋势影响较大,主流温度对壁温分布趋势的影响较小。
Comparison between S2 calculation, S1 calculation and FLUENT calculation illustrated that the mass flow and efficiency tally well, so does the distribution of mach number along the blade surface.
为校验所用S2 正问题计算和S1流面计算程序,对设计状态进行了S2 正问题计算、S1流面计算及FLUENT 计算,总参数如流量、效率等吻合较好,叶表马赫数分布趋势也很相似。
