摘　　要：以标准气流下降式密集式烤房为研究对象,通过正交试验分析方法设计三因素三水平试验,利用CFD模拟仿真方法对试验方案进行仿真计算。通过对仿真结果进行分析,得出当进风道角度为5°,进风道距离顶端0 mm,进风量20412 m^(3)/h时,装烟室内气流分布均匀性最佳。烤房装烟室内均匀的气流组织分布能达到更好的烘烤效果。This paper takes the standard airflow down-type intensive curing barn as the research object,and designs the threefactor three-level test through the orthogonal experiment analysis method,uses the CFD simulation method to simulate the test plan,and obtains the results after analyzing the simulation results.When the air inlet duct angle is 5°,the air inlet duct is 0 mm from the top,and the air inlet volume is 20412 m^(3)/h,the airflow distribution uniformity in the smoke chamber is the best.The uniform air distribution in the smoking room of the barn can achieve a better baking effect,which provides a strong basis for the design of the dense barn structure.
