Abstract

The interaction between oxygen absorption into liquids and bottom shear-induced turbulence was investigated in a grid-stirred tank using a laser-induced fluorescence (LIF) technique. The LIF technique enabled visualization as well as quantification of planar concentration fields of the dissolved oxygen (DO) near the air-water interface. Qualitative observation of the images provided more insight into the physical mechanism controlling the gas transfer process. The high data resolution is an advantage for revealing the concentration distribution within the boundary layer, which is a few hundreds of a micrometer thick. Mean and turbulent fluctuation characteristics were obtained and compared with previous results.
