Numerical simulation of blade erosion in particle-laden gas turbine in two-way-coupling turbulent field;
燃气透平气固双向耦合湍流场中叶片冲蚀的数值模拟
Numerical analysis and image processing were made by the established program system for the blade erosion prediction in particulate gas turbine of a pressurized fluidized bed combustion combined cycle power generation unit.
本文在含尘流透平叶片流道内气固两相流动数值模拟的基础上,发展了叶片冲蚀的数值分析方法,提出了便于工程应用的有限区域内质量加权、面积平均的冲蚀率统计分布计算方法;对建造中的江苏徐州贾旺增压流化床联合循环中试电站燃气轮机叶片冲蚀问题进行了数值模拟,给出了计算结果的数据图象资料,就叶片冲蚀状况进行了分析。
