摘　　要：针对多层住宅共用一个主烟道排油烟的实际情况,在建立烟道模型和烟道内两相流数学模型的基础上,通过fluent软件模拟住户排油烟时主、支烟道内的流场分布,并根据该流场分布特点研究对其上、下层住户的影响.结果表明:"串入"各层住宅的油烟中以对流裹携的油烟为主;排放的油烟对其上、下层住户所产生的影响轻、重不等,对底层住宅的影响尤为严重,而顶层住户所受的影响则较轻.According to the residenters useing only a main-flue in the multilayer building, the author simulates the liquid-field distributing by the CFD of fluent and studies the effect of exhaust system to the other floor, running character of the liquid-field distributing, based on the flue-model and the mathematics-model of two-phase flow in the flue. The result shows that the convection gas-oil flowing each floor is the most, the effect of gas-oil to each floor is different, especially, effect to the underfloor is larger and effect to the upside floor is small.
