| Abstract: | The paper analyses the gas porosity phenomenon in the piezoelectric valveless diffuser/nozzle based fluid pump discovered in the vibrating subcenter zone in high speed input process.The influence of fluid temperature change on the pump flow rate is explained by the gas porosity phenomenon,and a particular method for decreasing the gas porosity phenomenon by increasing the flow rate is demonstrated in experiments. |
