Abstract
The flow field created by two impinging liquid jets in a cylindrical chamber is investigated using particle tracing, laser Doppler anemometry, and three‐dimensional numerical simulation. The jet Reynolds number (based on the mean jet velocity and diameter) range is from 50–300. Results show that there is a threshold value of the Reynolds number beyond which the flow exhibits oscillations. Computer simulations agree well with the experimental visualizations, for both the overall observed flow pattern and a quantitative measure of the oscillations.Keywords
