ABSTRACT Potrooms are elongated buildings in which hundreds of aluminum smelting pots are housed, and have the particularity, among others, to be naturally ventilated. A CFD model simulating a potroom is developed to study its thermal comfort when the aluminum smelting pots take in less volume of air so as to facilitate waste heat recovery from the pot draft. The influences of wind and buoyancy on the ventilation performance of the potroom are simultaneously considered. The heat stress during hot weather is estimated for different cases. A 50% reduction in the pot draft rate is assessed in terms of its influence on the heat stress in the potroom. It is found the 50% reduction of pot draft will not cause a significant change in the ventilation pattern of potroom and the draft reduction can be realised without significantly increasing the potroom's heat stress.

冶金工业厂房不同工况下的气流与热应力

摘要 电解槽是细长的建筑物，其中装有数百个铝冶炼罐，具有自然通风等特点。开发了模拟电解槽的 CFD 模型，以研究铝冶炼罐吸入较少空气时的热舒适度，以促进从罐通风中回收废热。同时考虑风和浮力对电解槽通风性能的影响。针对不同情况估计炎热天气期间的热应力。根据其对电解槽中热应力的影响，评估了电解槽通风率降低 50% 的情况。
