Nozzle flowmeter is widely used in industry. In this paper, in order to study the influence of different flow rates and inner wall temperatures on the thermal effect and flow field of the nozzle flowmeter, the fluid-solid coupling numerical calculation of the thermal effect and flow field of nozzle flowmeter is carried out under four different flow rates and five different inner wall temperatures. It is found that, with the increase of flow rate, the heat transfer effect of the nozzle flowmeter is weakened under different inner wall temperatures. The pressure distribution in the fluid domain, the dynamic stress, and fluid-induced vibration deformation generated by the fluid of the nozzle flowmeter are less affected by inner wall temperatures.

基于流固耦合法的喷嘴流量计热效应研究

喷嘴流量计在工业中应用广泛。本文为了研究不同流量和内壁温度对喷嘴流量计热效应和流场的影响，进行了喷嘴流量计热效应和流场的流固耦合数值计算。在四种不同的流速和五种不同的内壁温度下。发现随着流量的增加，喷嘴流量计在不同内壁温度下的传热效果减弱。喷嘴流量计流体在流体域中的压力分布、动应力和流体引起的振动变形受内壁温度的影响较小。
