摘要
针对某化工企业的叶轮气动装置在生产中的废气利用效率低的问题,以Fluent流体仿真软件为基础,对叶轮气动装置的内流场进行数值模拟。通过分析内部流场的流速分布,压力分布情况,提出对进气口位置进行优化的研究方案,并采用数值模拟的方法,验证进气口位置改进的合理性。研究结果表明:改变叶轮气动装置进气口的位置能够使内流场分布趋于均匀,提高叶轮对过剩能源的转化能力。进气口位置改进后,有效提高了叶轮气动装置对废气的利用率。通过研究不同进气口位置对叶轮气动装置效率的影响,对叶轮气动装置进气口位置的加工工艺参数提供了参考。
Aiming at the problem of low exhaust gas utilization efficiency in the production of impeller pneumatic devices of a chemical enterprise,the research group used Fluent fluid simulation software as the basis to numerically simulate the internal flow field of the impeller pneumatic device.By analyzing the flow velocity distribution and pressure distribution of the internal flow field,a research plan for optimizing the position of the air inlet is proposed,and the method of numerical simulation is used to verify the rationality of the improvement of the air inlet position.The research results show that changing the position of the air inlet of the impeller pneumatic device can make the internal flow field distribution tend to be uniform,and improve the impeller's ability to transform excess energy.The improved position of the air inlet effectively improves the utilization rate of the exhaust gas of the impeller pneumatic device.By studying the influence of different air inlet positions on the efficiency of the impeller pneumatic device,it provides a reference for the machining process parameters of the impeller pneumatic device air inlet position.
