Abstract

A numerical computer code simulating the operation of a solar cooker of box type to solar concentrator was established. The computer code was used to study the effect of the thermal performance of the cooker. The aim of this work is to present a mathematical model of this solar cooker model in comparison with other models, and to analyze the various parameters that influence the cooker's thermal performance. The equations governing heat transfer in this solar cooker are deduced from the analogy between heat transfer and electrical transfer. These equations are discretized and solved by an implicit finite-difference method, using Gauss' algorithm coupled with an iterative procedure. he results show that an optimum solar flux of 900W/m² was used to determine the various optimum parameters. We deduce that the mirror is a good reflector, and for optimal dimensions of the parallelepiped enclosure [60cm*50cm*50cm], the thermal efficiency of the cooker varies from 42 to 45%. The influence of different pot wall materials shows that copper is a good conductor, and the influence of pot wall dimensions shows that a thin wall (3mm) increases thermal conductivity.
