With the spray combustion visualization test unit, researches have been made on the spray development process under different injection pressures with STD nozzles, VOC nozzles and IMPROVED nozzles of diesel engines. The result shows that with the rise of injection pressure, the spray cone angle increases slightly, and corresponding to the same injection moment, the penetration enlarges accordingly...
A versatile method of fabricating different microlenses using a relatively simple process is presented. A liquid-filled lens structure integrated with microfluidic network and liquid Polydimethylsiloxane (PDMS) are used as the frame and filling material, respectively, for the injection process. Through simply changing the injection pressure to obtain different membrane deformation profiles followed...
