Thermal modeling, energy and exergy analysis of animal feed solar cooker

This study deals with thermal modeling and experimental validation of animal feed solar cooker. The experiment was conducted for 9 months and found that a theoretical temperature is 2 to 3 °C higher than experimentally recorded. The value of correlation (r) coefficient for all months was 0.999, indicating that the developed model is capable of predicting the water temperature close to experimental values. Energy and exergy assessment of the cooker was also carried out. The experimental energy and exergy efficiency varied in the range of 23.19% to 28.25% and 1. 79% to 2.47%, respectively. The corresponding theoretical efficiency varies in the range of 24.22% to 28.33% and 1.97% to 2.88%, respectively.
