在这项研究中，一个标准尺寸为213cm × 243cm × 305cm的典型厨房被建模为单开门出口。稳态模拟使用三维商业CFD求解器与适当的边界条件。两个热源被用于模拟类似于发展中国家城市住宅厨房的双燃烧器燃气灶的厨房。在早期的工作中，对于同一模型，在最佳网格分辨率下验证了预测，并给出了自然、强制和无通风情况下的热舒适性、二氧化碳气体排放的结果。分析了抽油烟机系统对室内热舒适性和排放的影响。在本工作中，三个不同的位置的厨房油烟机的吸力已被研究的热分布和辐射率的影响。所研究的厨房抽油烟机的位置是相对于燃气灶的前面、顶部和底部。据观察，前面和底部的排气罩的方法显着减少排放量远低于安全限值。它们还可以在厨房空间内保持很好的热舒适性。
In this study, a typical kitchen having a standard dimension of 213cm × 243cm × 305cm was modeled with single open door exit. Steady state simulations were performed using three dimensional commercial CFD solver with appropriate boundary conditions. Two heat sources were used for modelling the kitchen that resembles the double burner gas stoves of urban residential kitchen in developing countries. In the earlier works, for the same model the predictions validated at an optimum grid resolution and the results have been presented for thermal comfort, carbon dioxide gas emission under natural, forced and no ventilation cases. The effect of kitchen hood system on the thermal comfort and emission has also been analyzed. In this present work, three different positions of the kitchen hood suction have been studied for the effect on thermal distribution and emission rate. The investigated positions of the kitchen hood are the Front, Top and Bottom with respect to the gas stove. It was observed that both front and bottom hood extraction method significantly reduces the emissions to well below the safe limit. They also can maintain thermal comfort quite well inside the kitchen space.
