摘　　要：基于Fluent软件和真实受感器模型,采用数值仿真的方法,建立了与受感器实际使用环境近似的流场计算域,研究了两种常见结构的受感器对流场总压场的影响,探索了受感器在不同工况下对流场不同位置的影响程度和流场沿程的总压分布情况,获得了一些关于受感器对流场总压场和沿程总压损失影响的结论,有益于指导后续的设计人员开展相关研究。Based on the Fluent software and the real sensor model, this paper adopts the numerical simulation method to establish a flow field computational domain that is similar to the actual use environment of the sensor. The influence of two kinds of sensors with common structures on the flow field total pressure field is studied. The influence of the sensor on different positions of the flow field and the total pressure distribution along the flow field under different working conditions are explored. Some conclusions about the influence of the sensor on the flow field total pressure field and the total pressure loss along the flow field are obtained, which is beneficial to guide the subsequent designers to carry out relevant research.
