Abstract

Steady state simulation of shell and tube heat exchangers has been carried out with Code FLOW3D. The code uses the finite volume numerical method. The control volumes are cuboids which are not necessarily parallelpiped and are transformed into rectangular grid using tensor algebra methods. The tube bundle and other internal parts are assumed to be a porous body. The governing physical laws are applied to the porous flow. Emperical formulae for loss in pressure have been used to model resistance offered by the porous body and the standard emperical heat transfer formulae to model heat source. The simulated flow field in vector form as well as the pressure, velocity and temperature contours are shown. The agreement between predicted and measured flow and tem
