Description 318-325
The present investigation is aimed to give a new dimension to the bubble column hydrodynamic study such as gas
hold-up, flow regime and total pressure-drop. Pressure swing rotating bubble cap (PSRBC) sparger is used for this purpose,
which has a unique feature of self-rotating ability. Compressed air is supplied through the PSRBC sparger into the column
of stationary water. Flow regime and gas hold-up of bubble column have been studied with various superficial air flow rates.
Empirical and semi-empirical models have been developed for predicting gas hold-up, pressure drop and RPM for the
PSRBC sparger bubble column in the present range of investigation. The calculated values from predicted models have been
compared with the experimental values and the coefficients of correlations are found to be more than 0.97. The present
hydrodynamic study on gas hold-up, pressure drop, flow regime and RPM may be found useful for the gas-liquid systems,
where the gas phase is dispersed in liquid through bubbling manner.
