Air entrainment as a result of a water jet plunging into a pool of water was studied by means of visualization techniques. Image processing algorithms were used to analyze the recorded sequences of the phenomenon. Data regarding the penetration depth and bubble size distribution was gathered for different jet impact velocities and jet lengths. The accumulated results are further used to validate the models implemented in computational fluid dynamics (CFD) codes.

Keywords: air entrainment; plunging jet; penetration depth; image processing; bubbles size distribution
