文摘

Mass transfer characteristics in and downstream of 90° elbow is studied. Mass transfer characteristics is measured by plaster dissolution method. Flow mechanism in elbow is studied by surface flow visualization. Velocity field is measured by stereo PIV downstream of elbow. Mechanism of mass transfer enhancement in elbow is examined.
