查询词典 nozzles

The pumps with different structural parameters are simulated numerically using k-ε model and wall functions. The results showed that the number of nozzles, the nozzle angle and the nozzle-to-throat clearance have a great influence on the performance of jet pump, and the turbulent kinetic energy is greater in suction chamber and in inlet of throat.

采用k-ε湍流模型和壁面函数法对不同参数下的多喷嘴射流泵进行了数值模拟，模拟结果表明，喷嘴数和喷嘴角度及喉嘴距对射流泵工作性能影响较大；在吸入室及喉管入口处湍动能较大。

The variable spraying control system took the S3C44B0X microprocessor of ARM7 series as its core control part and programmed with C language in the UCOS-Ⅱ environment.
