摘　　要：生猪运输车烘干房的主要目的是消灭转运车上的病毒、切断病毒传播途径,其能耗比较大。采用CFD软件对烘干房进行数值模拟仿真,同时进行实验,验证数值模拟的准确性,通过改变送风口和回风口的数量对初始烘干房进行结构上的改进。模拟仿真得出,烘干房内气流组织流动速度比以前提高到了0.9 m/s,升温时间缩减了50 s;工艺参数经正交试验得出最优的参数组合。The main purpose of the pig transporter is to eliminate the virus on the transporter and cut off the virus transmission path.The air flow velocity and uneven temperature distribution in the drying room of the transporter designed initially are problems,which causes the drying effect to be inferior.Ideal and energy consumption is relatively large.The fluent software is used to optimize the numerical simulation,and experiments are carried out at the same time to verify the accuracy of the numerical simulation.The structure of the initial drying room was improved by changing the number of air supply outlets and return air outlets.The simulation showed that the airflow velocity in the drying room was increased to 0.9m/s than before,and the heating time was also reduced by 50s;the optimal parameter combination is obtained by orthogonal test of the process parameters.
