In this work, the fluid flow, heat transfer, and combustion processes for a plancha-type biomass cookstove are numerically studied. This approach takes into account the numerical solution of mass, momentum, thermal energy, and chemical species conservation equations by using ANSYS Fluent™. Besides the fluid domain, a solid one representing the metallic comal is also considered for the simulations. In particular, numerical results for the CO₂ mass flow rate emissions, unburned volatile combustion efficiency (UVE), and thermal efficiency are compared with experimental Water Boiling Tests (WBT) data. For different firepower values, a good comparison is observed. Differences between numerical and experimental results are in the ranges of 2–9% and 1–2% for the CO₂ mass flow rates and combustion efficiencies, respectively. Results indicate that the thermal efficiency is higher for the low firepower cases, which is in agreement with experiments.

在这项工作中，数值研究了普兰查型生物质炉灶的流体流动、传热和燃烧过程。这种方法通过使用 ANSYS Fluent™ 考虑了质量、动量、热能和化学物种守恒方程的数值解。除了流体域​​外，模拟中还考虑了代表金属煤的实体。特别是，将CO ₂质量流量排放、未燃烧挥发物燃烧效率 (UVE) 和热效率的数值结果与实验水沸腾测试 (WBT) 数据进行了比较。对于不同的火力值，观察到一个很好的比较。对于CO ₂，数值和实验结果之间的差异在 2-9% 和 1-2% 的范围内分别为质量流量和燃烧效率。结果表明，低火力情况下热效率较高，与实验结果一致。
