PARABOLIC SOLAR COOKER DISH: DESIGN AND SIMULATION

Abstract

ABSTRACT A complete design and simulation of a parabolic dish solar cooker was carried out. The cooker can be used for boiling water as well as cooking in an isolation. A simulation model for transient state was introduced to predict the absorber (cooking pot), pot cover, cooking fluid and air gap temperatures. Linear regression was used to analyzed the data, an average standard error limit of 12.458345% and R2of 85.725% for the model was obtained which indicate a satisfactory agreement by comparison of experimental and theoretical result. An average instantaneous efficiency of 84% was determined at beam radiation of 650W/m2.
