Tffb Coupling Bem/Fvm Algorithm For Multi-Dimensional Conjugate Heat Transfer

Abstract

We develop a BEM-based temperature forward/flux back (TFFB) coupling algorithm to solve the conjugate heat transfer (CRT) which arises naturally in analysis of systems exposed to a convective environment. Here, heat conduction within a structure is coupled to heat transfer to the external fluid which is converting heat into or out of the solid structure. There are two basic approaches to solving coupled fluid-structural systems. The first is a direct coupling where the solution of the different fields is solved simultaneously in one large set of equations. The second approach is a loose coupling strategy where each set of field equations is solved to provide boundary conditions for the other. The equations are solved in turn until an iterated convergence criterion is met at the fluid-solid interface. The loose coupling strategy is particularly attractive when coupling auxiliary field equations to computational fluid dynamics codes. We adopt the latter method in which the BEM is used to solve heat conduction inside a structure which is exposed to a convective field which in turn is resolved by solving the Navier-Stokes equations by finite volume methods. Interface of flux and temperature is enforced at the solid/fluid interface.
