Experimental Research on the Water Spray Hole Flow Coefficient

Abstract The water spray hole flow coefficient is one of the important parameters that have great effect on the calculation accuracy of the spray water quality second flow. The test system is designed on the water spray hole flow coefficient in this study. The test results are obtained on the water spray hole flow coefficient under different working conditions. The results showed that the water spray hole flow coefficient is not constant but a function for time. The water spray hole flow coefficient increase with the increase of the number of blowhole. Although the rest results have a certain error, but this study fills the blank no test results on water spray hole flow coefficient. That also provides the technical support on improving launch internal ballistic calculation accuracy of the dynamical system and model improvement.
