Abstract

A general coupled algorithm is developed for the solution of the conjugate problem. A cooled turbine vane is considered and the fluid flow field and forced convection heat transfer external to vanes are resolved numerically by solving the Navier-Stokes equations using a cell centered finite volume method (FVM) on a non-skewed shifted periodic grid. The temperature within the vane is calculated by solving the conduction equation using the BEM. Conjugacy of external and internal temperature fields is accomplished by enforcing fluid/solid interfacial continuity of temperature and heat flux. An initial guess for the steady state external fluid flow and temperature is determined by subjecting the blade surface to an adiabatic condition. The
