本工作运用CFD技术的FLUENT软件建立了6HWF-20型高射程喷雾喷粉机的专用风机模型并进行了内部流场模拟,获得了转速为2372r/min时计算收敛后风机内部流场的速度矢量分布和压力分布情况,并通过优化风机叶片进口安装角和蜗舌的形状、尺寸,改善了风机内部流场。同时获得了6种转速下风机出口处的平均速度,并通过试验进行了验证。结果表明,模拟结果与试验结果吻合,基于FLUENT软件下建立的专用风机模型和模拟方法是可行的,为采用CFD技术进一步改善风机内部流场,提高风机出口速度,更有效地实现高射程喷雾喷粉功能具有重要的意义。
In this work, a dedicated wind turbine model of 6HWF-20 high-range spray dusting machine was established by using FLUENT software of CFD technology and internal flow field simulation was carried out. The velocity vector of the flow field inside the fan after convergence was obtained when the rotating speed was 2372r / min Distribution and pressure distribution, and improve the flow field inside the fan by optimizing the installation angle of the fan blades and the shape and size of the volute tongue. At the same time, the average speed of fan outlet at 6 speeds was obtained and verified through experiments. The results show that the simulation results are in good agreement with the experimental results. It is feasible to use a dedicated fan model and simulation method based on FLUENT software. In order to further improve the flow field inside the fan by using CFD technology, the fan exit speed can be increased and the high range spray spray can be more effectively realized Powder function is of great significance.
