Fossil fuels are vital in the cooking field rather than the automotive sector. Hence, solar cooking has been popularized in recent years due to the rising cost of cooking gas. However, implementing successful renewable energy for cooking in urban area is still challenging for industries. Hence, a solar thermic cooking device with a compact size suited for domestic cooking in urban area is proposed. Thus, the solar cooking device will be developed as a fully functional prototype with necessary supporting modules, depending on the heat transfer fluid (HTF) flow and heat transfer rate between fluids. The main objective is to represent various computational fluid dynamics (CFD) and thermal analysis results on different optimistic designs for a solar thermoelectric cooking device's heat exchanger and storage unit. The 3D part model of the modules has been developed using SOLIDWORKS 2019 software. CFD has also been carried out using the same workspace with an additional package called flow simulation to analyze the flow properties of heat transfer fluid at different rates when circulated in other modules. Moreover, the thermal behavior of the HTF concerning the heat transition between module surfaces is simulated using SOLIDWORKS flow simulation to evaluate the heat storage capacity and rate of heat transfer. The theoretical formulations for the modules are derived through thermodynamic equations concerning the materials and fluid involved in the unit. The thermal and CFD analysis is carried out for different optimistic 3D models based on thermal sustainability, and the results are compared with theoretical analysis, which is discussed in this paper.
化石燃料在烹饪领域而非汽车领域至关重要。因此，近年来由于烹饪燃气成本上升，太阳能烹饪得以普及。然而，在城市地区成功实施可再生能源用于烹饪对行业来说仍然具有挑战性。因此，提出了一种尺寸紧凑、适合城市家庭烹饪的太阳能热烹饪设备。这样，太阳能烹饪设备将根据传热流体（HTF）的流动以及流体之间的传热速率，开发成为具有必要支持模块的全功能原型。主要目标是展示太阳能热电烹饪设备热交换器和存储单元在不同优化设计下的各种计算流体动力学（CFD）和热分析结果。模块的三维零件模型已使用SOLIDWORKS 2019软件开发。CFD分析也是在同一工作空间中使用名为流动模拟的附加程序包进行的，以分析传热流体在不同速率下在其他模块中循环时的流动特性。此外，使用SOLIDWORKS流动模拟来模拟HTF在模块表面之间热传递方面的热行为，以评估蓄热能力和传热速率。模块的理论公式是通过与单元中涉及的材料和流体相关的热力学方程推导出来的。基于热可持续性对不同的优化三维模型进行了热分析和CFD分析，并将结果与理论分析进行了比较，本文对此进行了讨论。
