Abstract

We investigate the characteristics of a liquid jet ejected from an inclined tube, which is submerged immediately under a free surface. Jets are classified into three regimes: the curtain regime, transition regime, and column regime. In all regimes, the jet trajectories deviate from the standard projectile function. An important reason is that additive liquid is entrained from the bulk. The capillary force also contributes to the deviation in the curtain regime. Models are established to predict the horizontal distance that a jet travels above the free surface in the curtain regime and column regime.
