摘　　要：为比较常用的住宅厨房油烟机的适用性,以下沉式和侧面吸风式的新型厨房脱排油烟机以及浅吸式和侧吸式传统厨房脱排油烟机4种产品为例,运用CFD技术对厨房的油烟浓度场和速度场的分布进行了数值模拟,根据模拟结果对这4种油烟机的排烟效果进行了分析。分析结果表明下沉式新型厨房脱排油烟机的除油效果最好,传统的厨房脱排油烟机中侧吸式的除油效果要比浅吸式的好。In order to compare the applicability of range hoods for residential kitchen,the distribution of concentration and velocity is simulated.It is a case study of new range hood that is sunken type and side-draft type,and traditional range hood that is shallow attraction type and side inflow type.The smoke effects for four kinds of hoods are analyzed by simulation result.The result shows that sunken type hood is best in eliminated lampblack effect.Besides,side inflow type hood is better than shallow attraction type hood in eliminated lampblack effect.
