摘要
通风管道风机入口段空气流速较大,流动情况较复杂。对通风机入口管段进行数值模拟,掌握空气流动情况。在此基础上对几种优化流动措施进行数值模拟,对比分析结果表明气流转向处设置导流板的措施为最优,有利于减小气流在风管内扰动,降低流动阻力。
The air velocity of ventilation pipeline before ventilator inlet is greater,the flow in pipeline is complex. The results of simulation of air flow indicated complex after optimized solutions were applied to pipeline. The solution that reduce disturbance and flow resistance, it is optimal. flow. And the air flow is simulated placing flow deflector in corner can
