在利用轴流式水轮机全流道三维非定常湍流数值计算和利用弹性力学非稳态有限元法计算轴流式水轮机转轮叶片动态的应力和应变的基础上,利用弱耦合算法完成了轴流式水轮机在有粘有旋条件下的流固耦合计算,得到了叶片的动态应力和动态应变,并对结果进行了讨论。
Based on the pressure fluctuation forecast by unsteady turbulent simulation and the dynamic stress and strain computation by elastic mechanics non-steady finite element analysis, the loose coupling algorithm was used to carry out the fluid-structure interaction under the glutinous and vortex flow field in Kaplan turbine. Dynamic stress and strain of the blade were gained and discussed.
