摘要
在重力、浮力和阻力作用下建立了掺气水舌运动微分方程,并应用四阶龙格—库塔(Runge-Kutta)法得到其数值解;最后将挑流水舌外缘挑距计算值与原观值作了对比,其最大相对误差为3.4%.
A differential equation for aerated jet motion developed based on the application of gravity, buoyancy and resistanceis presented here which is solved then by Runge,Kutta method. At last,the calculated value of jet trajectory length was compared with the prototype measure value, their maximum relative error is about 3.4%.
