Vibration Analysis of a Counter-rotating Turbine with Week-flow by Fluid-Structure Interaction Method

摘要：

Counter-rotating turbine is one of new techniques to improve the thrust-weight ratio of jet propulsion engines. In this paper, numerical analysis of a low-pressure (LP) counter-rotating turbine rotor is presented by use of ANSYS/CFX software. Aerodynamics and solid mechanics coupling is applied in the computation, i.e. blade deformation changes CFD grid and pressure obtained form CFD simulation is applied to the blade surface. In this condition, stress distribution and vibration characteristics of the rotor blade are computed. Through this complicated numerical simulation, a process of fluid-structure coupling used in turbine is developed.
