摘　　要：针对现有的离心式除雪车出雪形状松散的状况,利用ANSYS CFX软件对离心式除雪车的扬雪管内流道进行气固两相流的数值模拟与分析,得到内流道中气固两相流的实际参数分析结果,并根据仿真实验结果针对几个结构参数进行优化.通过优化扬雪筒的结构形状确保雪在扬雪筒出口被抛出时有比较规范的形状,同时降低离心风机的功耗,提高抛雪效率.Aimed at the ruleless and loose shape of the removal snow that out of the existing centrifugal snow- clear machine, gas-solid two phase flow numerical simulation analysis of snow outlet piping internal flow field was provided by ANSYS CFX, and the conclusion of inner flow passage of gas-solid two phase flow is obtained by actual parameter analysis. The structure parameters of snow outlet piping are optimized based on the simulation resuhs. Through the mechanical structure optimization of snow outlet piping, ensuring snow has a fairy standard shape when it is thrown out of snow outlet piping, reducing power consumption of snow throwing centrifugal fan device and improving the efficiency of throwing snow at the same time.
