摘　　要：针对某款烟熏炉在使用过程中出现的烟熏效果不佳、加热仓内上下2部分食物蒸煮不均匀的问题,采用CFD技术,依据烟熏炉结构特点与加工要求,研究加热仓的气流场仿真分析的建模方法。提出采用二维简化建模分析方法,提高计算效率。根据加热仓气流场的仿真结果,论文提出了在加热仓进风口增加导流板结构的方案。仿真与实验结果表明:导流板有效地改善了加热仓内的流场分布,有助于克服加热仓内流场分布不均匀导致的食品加工效率低的问题。该研究具有良好的实用价值。According to the shortcoming of that the smoking effect is not good and the food of upper part and lower part in heating bin can＇t be smoked simultaneously in the use process of some a fumigation oven,this paper studied modeling method of air flow field for simulation analysis based on to the structural characteristics and processing requirements of the fumigation oven,using CFD techniques. The paper put forward a method of 2D simplifying modeling and analysis to improve the simulation efficiency. According to the simulation results of the air flow field,this paper gave out a kind of deflector structure. The simulation and experimental results showed that the deflector had a good practical value to solve the problem of the lower efficiency caused by uneven distribution of flow field.
