Abstract

The entrainment of air into spray jets has been considered. Entrainment is defined as the quantity of ambient gas that is drawn into a spray. Numerical study is performed to investigate an air entrainment into spray jets and compared with results of experiment of air entrainment. Experimental measurements were performed with PDA and PIV system. Experimental and numerical results show that the air entrainment was affected droplet size and velocity.
