“…In addition to the traditional method of improving the performance of SBC by adding a reflector(s), the performance of SBC is also improved by modifying the cooking pot [13][14][15][16][17] or adding materials to the inside of the cooker. [18][19][20][21][22][23] The performance of SBC is evaluated by several parameters, including Performance Characteristics, First and Second figures of merit, Time Boiling, Parameter Index, Standard Cooking Power, cooker optothermal ratio (COR), Thermal efficiency, and Exergy efficiency. [24][25][26][27] Mawire et al 28 compared two SBCs with a reflector and without a reflector by evaluating both energy efficiency and exergy efficiency with several water loads.…”

The use of fossil fuel and wood for cooking poses health, environmental, and economic challenges, especially with the growing population. This has led to an increase in the trend towards the use of clean and sustainable cooking sources, including solar cookers. This experimental study aims to contribute by enhancing the performance of a solar box cooker (SBC) according to the concept of porous media via adding steel fibers inside the box as a modified SBC and comparing it with a conventional SBC. The stagnation test to determine the first figure of merit and the load test to determine the second figure of merit, standard boiling time, and cooker optothermal ratio were conducted under the outdoor conditions of Baghdad city. Also, an energy and exergy efficiency analysis, and calculating the rate of heat loss by three water loads heating and cooling tests. The results revealed that the modified SBC has a higher thermal performance than the conventional SBC.

“…TES systems combined with solar cookers can be advantageous during non-sunshine periods. In recent years, researchers have extensively investigated solar cookers integrated with TES systems [19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Saxena and Karakilcik evaluated a solar cooker with low-cost storage material [19].…”

“…The results showed that the PCM improved the load thermal stabilization during off-sunshine periods. Palanikumar et al [28] investigated a solar box-type cooker with nanocomposite PCMs using flexible thermography. The experiment aimed to compare a solar box cooker with PCM, one with nanoparticles PCM, and one without nanoparticles PCM.…”

Experimental Energetic and Exergetic Performance of a Combined Solar Cooking and Thermal Energy Storage System

Most solar cookers usually perform a single task of solely cooking food during sunshine hours. Solar cookers coupled with thermal energy storage (TES) material for off-sunshine cooking are usually expensive and require complex engineering designs, and cannot be used for dual purposes, for example, solar water heating and cooking. In this paper, a solar cooker that can perform dual tasks of cooking as well as storing thermal energy to be used during off-sunshine periods is presented. The experimental setup is composed of a parabolic dish, a solar receiver coupled with a flat plate and an oil-circulating copper coil for charging and discharging a storage tank. The objective of the experiment is to evaluate the energy and exergy thermal performance parameters of the dual-purpose system during charging and discharging cycles. The effect of the flow rate and the mass of the load are investigated while using sunflower oil as both the heat transfer fluid and the storage material. Charging and discharging experiments are conducted using four different flow rates (2, 3, 4, 5 mL/s), and with different masses (0.5, 1, 1.5, 2.0 kg) with water and sunflower oil as the test loads. The charging results show that the average energy and exergy rates as well as their corresponding efficiencies increase with an increase in the charging flow rate. On the other hand, the increase in the mass load tends to decrease marginally the average charging energy and exergy rates for water, and their corresponding efficiencies. For sunflower oil, the average charging energy and exergy rates and efficiencies showed a more pronounced decrease with an increase in the mass. Water generally shows higher charging and discharging energy and exergy efficiencies compared to sunflower oil with an increase in the flow rate. For discharging results, the correlations between the energy and exergy thermal performance parameters with respect to the flow rate and the heating load are not well defined possibly due to different initial storage tank temperatures at the onset of discharging and the inefficient discharging process which needs to be optimized in future.

“…Palanikumar et al 4 made three solar box cookers using with and without nanocomposite for the phase change materials (NPCM). Analysis of experimental performance for that overall efficiency by the system is used without NPCM, with PCM, and with NPCM, which is obtained as 24.90%–33.90%, 24.77%–45.20%, and 31.77%–56.21%.…”
