numerical analysis of fluid structure interaction phenomenon on a turbine blade

in this paper, the fluid-structure interaction phenomenon and the research history are described. then due to the complex and specific working conditions of a turbine blade, we have investigated the phenomenon on this subject. the fluid-structure interaction on a turbine blade model has been simulated by using structural and fluid flow section of ansys software. a model of turbine blade with airfoil cross section made of aluminum has been analyzed in three different inlet speed of the fluid. for analysis results the amount of turbine blade tip deviation and its impact on the fluid flow pressure exerted on the turbine blade has been considered. the results show that by increasing the speed of inlet flow, the amount of blade tip deviation increases and also its impact increases on fluid pressure exerted on the rotor. the results also show that the transverse displacement of the blade is linear across of its axis.
