【摘要】 该文利用准定常模拟实验系统,对侧孔流量系数进行了较为系统的实验研究,依据发现的侧孔流量系数随侧孔倾角和孔径的变化规律,获得了一个简单而实用的流量系数的经验公式.更多还原

【Abstract】 An experimental investigation on discharge coefficient of gas port was performed sys-tematically by use of a quasi—steady test system.The experimental results show that the regu-larity of discharge coeffictient of gas prot with both the angle and diameter of gas prot.Anempirical formula of the discharge coeffictient is obtained.更多还原
