| 摘 要： | 联合采用FLUENT和ANSYS分析软件对具有典型节流槽的非全周开口滑阀的三维流场、液-固温度场和固体热变形进行数值计算.结果表明:非全周开口滑阀内部流体和固体内的温度分布不均匀,阀口流束在接近固体壁面的区域温度较高,流束中心部位温度较低,阀体和阀芯在阀口附近及流束冲击壁面有局部高温,由此导致的阀芯和阀体不均匀变形量可...

| Abstract: | The three-dimensional flow field,solid-liquid temperature field and solid thermal deformation in a spool valve with typical throttle notches were calculated by using the combined softwares FLUENT and ANSYS.The numerical result showed that the temperature distribution of the fluid and solid was nonuniform in the spool valve.The temperature of the jet flow near the solid wall was higher and the temperature at the jet center was lower.In addition,the highest temperature took place on the solid wall near the or... |
