Correction of the Effective Thermal Conductivity of Two Phase System using Resister Model with Cylindrical Inclusions

ABSTRACT The study of heat transfer through two phase materials from the values of thermal conductivity of the constituent phases and there volume fractions. The resister model has been applied to determine the effective thermal conductivity (ETC) in this arrangement has been divided in to unit cells, each of which contains a cylinder. The random packing of Phases, non-uniform shape of particles and the flow of the heat flux lines not restricted to be parallel, we replace physical volume fraction of solid phases by porosity correction term F. In this paper, we calcute the effectivity thermal conductivity using a Jagjiwan & Singh model with correction of this model. Comparison of the predicted values of the correlations with experimental results is also made. The predictions of effective thermal condivity of two phase materials match well with the good experimental results.
