    • A double-acting device for generating a synthetic jet is provided. The double-acting device includes a chamber having a cavity for a working fluid, a separating element for dividing the chamber into at least two sub-chambers, a control system connected to the chamber for controlling the separating element to act reciprocatingly, an input system connected to the chamber for inputting the working fluid to the chamber therethrough and an output system connected to the chamber for outputting the working fluid from the chamber therethrough. When the working fluid is pushed and pulled by a reciprocating action of the separating element, a train of vortices would be puffed and a non-zero-net-mass-flux fluid is generated through a designed structure and a defined arrangement of the input system and the output system.
    • 提供了一种用于产生合成射流的双作用装置。 双作用装置包括具有用于工作流体的空腔的室,用于将室分成至少两个子室的分离元件,连接到室的控制系统,用于控制分离元件往复运动,输入系统 连接到腔室,用于将工作流体输入到腔室,以及连接到腔室的输出系统,用于从腔室通过其输出工作流体。 当通过分离元件的往复运动来推动和拉动工作流体时,一系列涡流将被膨化,并且通过设计的结构和输入系统的限定布置产生非零净质量流量的流体 和输出系统。

    • A high-precision vortex flow meter includes a blunt body having a predetermined dimension and being arranged inside a fluid channel to serve as a vortex shedder. The vortex flow meter also includes a temperature detecting device for detecting the vortex shedder temperature and a temperature control element for adjusting the vortex shedder temperature. A frequency measuring device is arranged in the downstream section of the blunt body for detecting the vortex shedding frequency. From the measured temperatures of the upstream fluid flow and that of the blunt body, an effective temperature and a temperature ratio are calculated. The kinematic viscosity of the fluid is looked up from database. By using the relationship between the Strouhal number and Reynolds number, the fluid flow rate is calculated. By employing different blunt body temperature, the measurement range of the flow meter can be broadly extended.
