摘要(Abstract):

为了研究柱塞式高温掺合阀在实际生产中流体域内温度场、速度场、压力场及阀耦合温度场的分布规律,分别采用理论计算方法和基于ANSYS的有限元方法对实际生产工况条件下该阀的流场、温度场进行耦合计算。给出了理论计算过程,为模拟分析提供依据,给出了流体域内温度场、速度场、压力场及阀耦合温度场的计算过程和结果。结果表明:阀内流体域分布中速度场分布与温度场分布整体吻合,态势良好;热流出口段窗口处温度梯度较大,且由于热流段流速较快,耦合过程中有一定射流现象;热流入口处沿径向温度梯度较大,说明隔热件发挥作用,隔热效果较为明显。
In order to study the distribution law of temperature field,velocity field,pressure field and valve coupling temperature field in the fluid field of plunger type high temperature mixing valve in actual production,the theoretical calculation method and the FINITE element method based on ANSYS are used respectively to carry out the coupling calculation of the valve’s flow field and temperature field under working conditions.The theoretical calculation process is given,which provides the basis for simulation analysis.The calculation process and results of temperature field,velocity field,pressure field and valve coupling temperature field in fluid domain are given.The results show that the velocity field distribution and the temperature field distribution are in good agreement as a whole with good trend;The temperature gradient at the exit window of the heat flow section is relatively large,and there is a certain efflux phenomenon in the coupling process due to the faster flow velocity of the heat flow section.The temperature gradient along the radial direction of the heat flow inlet is relatively large,indicating that the rigid jade thermal insulation parts play a role and the thermal insulation effect is more obvious.
