Experimental analysis and simulation of the performance of a box-type solar cooker

A box-type solar cooker was tested and modelled during a long time period in Madrid (Spain). The experimental data were employed to obtain the convective coefficients of the heat transfer model proposed. The model was validated with experimental data, obtaining results with a relative error under 4% during a whole month of temperature measurements. The model was also employed to simulate the performance of the solar cooker for a year in several countries around the world, estimating the number of days per year in which the solar cooker can be operated in each location. The results obtained from the model informed of the high potential of solar cooking in developing countries.
