为了探明某鸡舍过滤装置内部流场及压力场的分布情况，应用计算流体力学方法对过滤装置内部流场进行仿真计算及分析，并搭建试验台进行测试，对仿真结果进行验证。研究结果表明减小过滤装置进气口与出气口角度，并且将突缩段做变径处理能够有效改善过滤装置的流场与压力场分布，经改进后的装置流阻损失减小8%。此过滤装置还适用于过滤进风口面积小、风速高的场合，如数据机房等。

In order to investigate the flow field and pressure field distribution inside the interior of the air filtration unit forhen poultry houses,appliesthe com putationalfluid dynam icsm ethod to calculate and analyze the internalflow field, and builds the test bench to validate the sim ulation results. T he results indicate that it can effectively im prove the flow field and pressure field distribution w hen the angle betw een the inlet and the outlet is reduced and w hen the size of the sudden contraction section changes gradually. T he flow resistance can be reduced by 8% after the im provem ent of the device.T his filter is also suitable for the applications w here the inletarea for air filtration is sm alland the air velocity is large,such as the data room .
