Abstract
The purpose of this investigation is to understand flow characteristics in
mini/micro sonic nozzles, in order to precisely measure and control miniscule
flowrates. Experimental and numerical simulation methods have been used to
study critical flow Venturi nozzles. The results show that the nozzle?s size
and shape influence gas flow characteristics which leading the boundary layer
thickness to change, and then impact on the discharge coefficient. With the
diameter of sonic nozzle throat decreasing, the discharge coefficient
reduces. The maximum discharge coefficient exits in the condition of the
inlet surface radius being double the throat diameter. The longer the
diffuser section, the smaller the discharge coefficient becomes. Diffuser
angle affects the discharge coefficient slightly.
