Temperature Effects on Generation and Entrainment of Bubbles Induced by a Water Jet

Abstract

Quest Integrated, Inc., Appl. Phys. Div., 21414 68th Ave. S., Kent, WA 98032, USA J (Journal-Article) M (Marine) A simple experiment simulating the jet feature of breaking waves is conducted to study quantitative effects of the water temperature on the generation of bubbles at the air-water interface and their entrainment into the water column. The results indicate that there is a critical water temperature for the inception of bubbles. Such a critical temperature can be attributed to changes of the surface tension and viscosity, both of which decrease as water temperature increases. Field measurements of the bubble entrainment depth, bubble size spectrum, and whitecap coverage are shown to have similar temperature dependencies as our observations ASFA 2: Ocean Technology, Policy and Non Living Resources (Q2) 2661066 -------------------------------------------------------------------------------- Record 967 of 1621 - ASFA 1988-1996
