“…Solar Cooking Archive [8] also gives several reviews on solar cooking and recent developments. Many authors who have tested various types of solar cookers have concluded that the box-type cooker shows great promise due to its efficiency, ease of operation, low cost and as most are usually made from locally available materials [4,9]. Several researchers are now focusing their studies on improving the efficiencies of simple and lowcost solar cookers.…”

“…The overall efficiency of the novel solar cooker was found to be 29.5%. Ibrahim and El-Reidy [9] designed a box-type solar cooker and evaluated its performance for use in the Egyptian climate where they found that a good meal for four people could be cooked in 3-4 h. Biermann et al [15] performed 1-year comparative tests on seven different types of solar cookers in South Africa. Measurements revealed an overall fuel saving of 38%.…”

SUMMARYThe performance of a low-cost compound box-reflector solar cooker designed and constructed by the department of Mechanical Engineering, at the University of Zimbabwe, was investigated and evaluated using a microcontroller-based measurement system over a period of 3 months. Solar radiation and temperature measurements are sent directly to the computer for monitoring and subsequent analysis using a spreadsheet program. The system is connected to the computer through the RS232 port. Temperature was measured by LM335 temperature sensors, whereas solar radiation was measured by a Kipp & Zonen CM3 thermopile-based pyranometer that was initially calibrated against the Eppley Precision Spectral Pyranometer. Peak temperatures of about 901C for the food can be attained in about 5 h on a clear day in Bindura, Zimbabwe (181S, 311E). A standardized cooking power of 11 W and an overall efficiency of 15% were found for this cooker.

“…Research also proposed that stainless steel and aluminum vessels can be used with black paint. Said and Medhat [16] recommended formulae for calculating orientation angle and tilt angle of the reflector of the sun-based cooker. El-Sebaii et al [17] literature answered to build up a mathematical model for a box type sunlight-based cooker with external and inward reflectors.…”

“…Suresh et al [37] proposed a semi-log plot method and an approximate method to find 2 known as second figure of merit of box-type solar cookers. Ibrahim and Medhat [16] used the standard procedure of cooking power and analyzed a box type solar cooker to adjust four cooking pots under different weather conditions prevailing at in Tatna (Egypt) during July 2002.The cooker has the ability to cook variety of food with a utilization efficiency of 26.7%. A simple test procedure for the determination of various design parameters was proposed by Kumar [38] used for the prediction of thermal performance of box-type solar cooker.…”

Cooking is one of the most common activity in day-to-day life of every woman. In rural areas the transportation of fuel is major problem and the increasing demand of energy for cooking applications is gaining importance and various investigations are being carried out for performance enhancement of the solar cooker. The box-type solar cooker has a complex thermal analysis due to the transient heat transfer phenomenon involved in three dimensions. A comparison of the standard correlation available are analysed for accuracy of predicted results with experimental data. The investigation involves the experimental determination of the parameters viz. wind heat transfer coefficient, side and bottom loss coefficient, inner and outer glass temperature. The extensive data is analysed with that of standard correlations and the significance of the experimental data is checked. Analysis found to have deviation of 3%-20% in experimental and correlation data, which indicates that for accuracy of performance analysis the studied parameters should be determined experimentally.

“…Research has also been done on double glazed solar oven which takes radiation only from the top surface [4], [5]. A simple box type solar oven has been created in Egypt and its performance was studied [6]. For thermal performance testing of solar cooker mathematical models have been presented by Garg et al [7], and Vaishya et al [8].…”

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.
