A THEORETICAL AND EXPERIMENTAL STUDY

Abstract

A Iheoreticat and experimental model which describes the transient behaviour of a matrix solar air heater is presented. The transient behaviour of the heater results from sudden changes in the intensity of the incident solar radiation and the inlet fluid temperature. The temperature distributions in both the fluid and the solid matrix domains are given exactly, and experiments are conducted to verify the validity of the theoretical model. There was good agreement between the measured and predicted values.
