“…The upper limit of the water temperature for the time period analysed cannot be taken as 100˚C (the boiling point at atmospheric pressure) because the rate of variation of water temperature approaches zero as the water temperature approaches 100˚C. Therefore, the upper limit of sensible heating (T w2 ) has been fixed in the temperature range 90˚C -95˚C (Mullick et al, 1987) [7]. The data recording was continued until the water temperature reached about 95°C as per suggestion of BIS [5].…”

“…[5,6]. Funk et al (1998) presented a parametric model of solar cooker performance based on three controlled parameters (solar intercept area, overall heat loss coefficient, and absorber plate thermal conductivity) and three uncontrolled variables (insulation, temperature difference, and load distribution) [1].…”

“…Telkes (1959) has designed, fabricated and tested some excellent models of solar cookers incorporating features such as mirror boosters, inclined aperture and side loading [2]. Mullick et al (1987) outlined a test procedure for the solar box cooker. They have developed methods of evaluating box type solar cookers using two figures of merit.…”

Abstract-A detailed experimental study has been carried out to investigate the effect of spacing between absorber plate and glass cover (that is height of the cooking chamber) in a domestic box type solar cooker. In order to investigate the effect of spacing between absorber plate and glass cover, 10 cm spacing and 8 cm spacing between absorber plate and glass cover have been compared with 12 cm spacing which is available in a normal domestic box type solar cooker. By reducing the spacing between absorber plate and glass cover heat transfer to cooking food increases very much. This enhancement in heat transfer is due to enhancement in convective mode of heat transfer mainly. By reducing the spacing between absorber plate and glass cover; bulk, weight and cost of solar cooker can be reduced considerably.

“…The Figures of merit (F 1 and F 2 ) for the box cooker suggested by Mullick et al, [15] and can be described as: the first Figure of merit is the optical ratio efficiency and overall heat loss coefficient for a SBC and experimentally, it can be termed as equation (5), while second Figure of merit can be expressed as equation (6) …”

Abstract:A solar box cooker (SBC) has been developed for the thermal performance evaluation by operating it on a low cost thermal storage. For this, a mixture of sand and granular carbon has been prepared and tested for an optimum ratio under a solar collector. After testing, the ratio of 4:6 (sand: carbon) has been observed to maintain a high temperature range with long term heat storage. This mixture has been used as thermal heat storage inside the SBC. The experimentation procedure has been conducted under climatic conditions of Moradabad, India. Results indicated that the first Figure of . The system was found feasible for cooking during the off sunshine conditions.
