Abstract

   Simultaneous measurements of local velocity and temperature in a vertical bubble driven plume have been done by using a Laser Doppler Velocimetry(LDV) on velocity measurement and thermistors on temperature measurement. In the first, instantaneous velocity including turbulence and fluctuation induced by bubbles was revealed, and counter-gradient diffusion of momentum. In the second, scalar transport in a vertical bubbly plume was measured and it was found that bubble movement generated isotropic mixing.
