摘要
以动量定理为基础,建立了倾斜侧吹射流轴轨迹的数学模型。模型的主要特点是,对于侧吹倾斜射流,推导出无因次射流轴轨迹的微分方程。对于空气向水中喷吹,数值计算表明,本计算轨迹与实测射流的轴线一致。
Based on the momentum theorem,a mathematical model is developed to desc-ribe the trajectory of a side--blown gas jet slanting in liquid. A dimensionlessdifferential equation is thus derived to characterize the axis trajectory forsuch a slanting gas jet. Numerical results show that when injecting aim intowater the jet axis measured is well conform to the trajectory calculated.
