This thesis examines the splashing of water drops on a water surface and the entrainment of air by a jet plunging into a liquid pool. Both these
phenomena have been examined photographically and
as a result mechanisms have been proposed for them
both. Models based on these suggested mechanisms
have been tested against experimental data.
Measurements have been taken of air entrainment rates and a correlation suggested relating this to the
properties of the jet. The model of the air
entrainment rate as a function of jet roughness has been confirmed and another proposed for the rate of air entrainment as a function of bubble penetration depth into the pool.
A Doctoral Thesis. Submitted in partial fulfillment of the requirements for the award of Doctor of Philosophy of Loughborough University.
