In this paper we obtain a mathematical thermal model to explain the behavior of the solar cooker: "Jorhejpataranskua". The model is shown in terms of a coupled system of three non-linear differential equations. We calculate temperatures for the fluid, the reflectors and the container of the solar cooker, and then compare the numerical results obtained with the model to measurements in field-testing operations and obtained results that agree with the experimental data. Finally, we use numerical results to calculate the cooking power and standardized cooking power of the solar cooker for two different containers.

“…Box type solar cookers have attracted the attention of many researchers. It can be found amount of research about design of hot box type solar cooker in literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. It is more commonly used than the concentrator type for cooking at noon since it is both cheaper and simpler to construct and operate.…”

“…For thermal performance testing of solar cooker mathematical models have been presented by Garg et al [7], and Vaishya et al [8]. Theoretical model have also been presented for double glazed solar oven receiving solar radiation from two sides [9], [10]. Yadav and Tiwari [11] carried out a transient analytical study of box type solar cooker with one surface exposed to solar radiation.…”

Abstract-This paper investigates the thermal performance of a unique box type solar oven whose five sides are exposed to ambient and provisions are also provided to install the reflectors to enhance the intensity of incident solar radiation on the oven. Experiments were performed where temperatures attained inside the box cavity are recorded on different days and times of the day corresponding to various intensities of available solar radiation. A steady sate heat transfer numerical model of the solar oven without reflectors is also developed based on six individual thermal resistance networks which account for the heat losses through each flat-side of the oven box and a good agreement with the experimental data is achieved. A parametric study based on numerical calculations and experiments is then carried out to study the effects of various parameters on oven's thermal performance, e.g. number of glazings, distance between glazings and box, type of absorber coating, etc. Higher box temperature is attained using double glazing than single glazing. As compared to black paint, selective surface coating results in significantly higher oven temperatures (up to 40 o C). Plate spacing of 20-30 mm is found to be optimum distance between oven box and glass covers.Index Terms-Solar oven, oven box temperature, reflectors, overall heat transfer coefficient.
