An experimental study of an air-water bubbly turbulent flow in a                vertical pipe will be conducted.  Small uniform bubbles will be                 generated in concentrations less than 10 percent, making for a                  well-defined departure from single-phase flow in the same                       geometry.  Liquid-phase mean-floor and turbulence parameters will               be measured by hot-film aneometry, with moving-window statistical               techniques to determine acceptance criteria for data.  Radial                   profiles of bubble concentration and size distribution will be                  obtained optically, using image digitization and spatial                        filtering to enhance edge contrasts.  i) The radial void fraction               data will be compared to data obtained elsewhere with intrusive                 probes.  New information on the production, transport, and                      dissipation of turbulent energy by the bubbles is anticipated.
