The small 10.8 cm diameter Plexiglas slurry bubble column has been operated in various modes and in different environments. With minor refinements in instrumentation, it has been used to measure heat transfer coefficients between a heat transfer probe bundle containing five 19 mm outer diameter and 188 cm long Plexiglas tubes and the air-water system. The heat transfer coefficients are reported for the central tube of the bundle which contains a 34 cm long heated brass section as a function of air velocity (0.04 to 0.42 m/s) and for different heat flux values. Data are also obtained as a function of time during which the system tends to move to acquire the steady state. Hydrodynamic condition of the column is also established by taking the gas holdup data, both average and local along the column, as a function of air velocity, water column height, and with and without the probe bundle in the column. Based on this experience an improved design for the single probe has been developed both for its fabrication as well as for its mounting in the column. The construction and installation of the probe is completed and a bulk of the elaborate heat transfer and hydrodynamic measurements are also completed as a function of operating and system parameters. 12 figs., 4 tabs.
