Hello all- First post. I am curious if it is possible to create cavitation underwater with these specific criteria. I am basically using a venturi device that will be pulled underwater in saltwater. Is it possible to get the vapor pressure down low enough to boil water (make bubbles). I have done some rudimentary calculations and I got some Reynolds number in the 132,000 range which would be quite turbulent flow. Here are the parameters of my question: Venturi inlet diameter is .7500 inches (cannot change this....hopefully) Venturi throat is .0937 inches (3/32) in diameter. (this can diameter can change) The total length of venturi device is 1" 3/8" The Venturi will be operated at depths of 10 feet to 50 feet below the surface of salt water The Venturi will be operated in salt water with a temperature of 5 degrees C to 20 degrees C The Venturi device will be moving from 2-5 knots consistently underwater. 3 knots is 1.543 meters/ second Venturi will be made of yellow brass. Optimum bubble diameter would be between 1/8" to 1/4" My two questions are: 1. can I make consistent bubbles underwater? 2. Specifically can I make NON-destructive cavitating bubbles with the above criteria?
