Abstract
Establishes throttling model of multi-hole orifice(MO).Based on the study of main factor affecting MO throttling characteristic,conducts throttling experiment using water as medium.In order to contrast the experimental effect,testing MOs and standard orifice(SO) are both investigated in throttling experiment under various equivalent diameter ratio and diameter ratio.The model form is determined according to the theoretical throttling model of SO then the unknown parameters are identified by means of experimental data analysis.MO throttling model is provided while it agree wells with another experimental results.
