Description
A microbubble generation system has been designed, constructed, and tested in a
circulating water tunnel. A 1.0 m long flat plate was subjected to a flow where the
Reynolds number ranged from ReL = 7.23x 10^5 - 1.04 x 10^6. Bubble diameters and skin
friction measurements were studied at various airflow rates and water velocities.
Bubbles were produced by forcing air through porous plates that were mounted
flush with the bottom of the test plate. Once emitted through the plates, the bubbles
traveled downstream in the boundary layer. The airflow rate and water velocity were
found to have the most significant impact on the size of the bubbles created.
Skin friction drag measurements were recorded in detail in the velocity and
airflow rate ranges. The coefficient of skin friction was determined and relationships
were then established between this coefficient and the void ratio.
