【摘要】 研究了空中水舌视为水气两相流在重力和空气阻力作用下的抛射运动。给出了掺气水舌运动轨迹方程、水平射距公式以及掺气水舌的入水角、入水速度和曲线长度表达式。文末进行了工程实测资料与计算对比,结果表明:建议公式的计算值与原型观测值甚为接近。更多还原

【Abstract】 This paper investigates the projectile motion of the jet flow in open air which is regarded as the two—phase flow of water—gas mixture under the action of gravity and resistance force of air. The equation of orbital motion of aerated jet flow, the formula for the horizontal length of jet flow, the inflow angle and velcoity of aerated jet flow and the expression of the length of its curve are given. At last, the comparisom between the calcrlated and the actual measured values in engineering structure is pretty close.更多还原
