Abstract:This study firstly defines a set of arrangement rule for perforated holes of multi-hole orifice (MO), and then presents three critical geometrical parameters including total number of perforated hole, equivalent diameter ratio and distribution density of perforated holes, which are to quantify MO structure. This paper built the throttling test apparatus for nice test MO plates, which were designed according to orthogonal theory. The experiments were conducted to investigate the effect of three critical geometrical parameters on the pressure loss coefficient of test MOs. Results show that equivalent diameter ratio is the dominant parameter affecting MO throttling characteristic.
