Abstract: In this work, we present thermal-FSI analysis of a power turbine guide vane of turbine helicopter engine PZL-10W. Firstly, CFD conjugate heat transfer analyses were carried out, then stress analyses were performed with boundary conditions obtained via CFD analyses. Influence of turbulence RANS models on heat transfer coefficients and stress distribution were investigated in detail. We used eddy-viscosity SST and γ - ReΘ SST transition models and two second closure: RSM and WJ-BSL-EARSM. In addition, effect of mass flow rate of rotor disc cooling fluid on stress distribution was examined. Moreover, we discuss heat flux convergence in vane on temperature and stress distribution. In order to model a material effort, the Burzynski parabolic model was implemented.

Keywords: thermal-FSI; conjugate heat transfer; thermal stresses; turbine guide vane; Burzynski stresses; influence of RANS on stresses; convergence of heat flux.
