Description
Based on isentropic equation, this paper analyzed the transient flow of compressible fluid, and derived the calculation formula of flow field in space pipe. Using software developed to calculate the flow field of selected elbow and tee, and calculation results showed that the accuracy of gas hammer software developed was high enough for engineering. Through the calculation of a space pipe constructed referring to the main stream system of a nuclear power plant, the relationship between the pipe internal pressure and the velocity fluctuation with space pipe boundary as well as the valve switch time obtained. Moreover, the gas hammer software developed is more convenient for constructing space pipe and less consumption of time during calculation. (authors)
