Abstract
- Abstract: This paper describes a steady numerical flow model and experimental gas flow results of a self-encapsulated, piezoelectrically actuated, cryogenic micro-valve for distributed cooling applications. Experimental flow data of the prototype micro-valve design is obtained for various gases at room temperature and for helium at near liquid nitrogen temperature. With a pressure differential of 100kPa across the inlet and outlet, a prototype micro-valve is shown to modulate the flow of room temperature helium from 1200 to 0sccm. Numerical flow results and experimental data agree well, with 60% of the data points falling within the range of ±10%. [Copyright &y& Elsevier]
