Abstract
This thesis describes experiments involving a gas-water analogue of internally heated boiling pools in which capillary tubes are used to obtain a continuous, volumetric addition of gas bubbles to a pool of water. Measurements of superficial velocity versus average void fraction for two different injection site densities and several pool heights were obtained. This data was compared to data obtained by gas injection employing a perforated plate. Superficial velocities at the flow regime transition for the two different injection techniques were compared with each other and with transition criteria which has been proposed in previous studies for both bubbly and dispersed flow. Local void fraction as a function of vertical distance from the bottom of the pool, was determined for both planar injection and volumetric injection of the gas with various initial pool heights, flowrates, and flow regimes. The two different injection techniques were compared to each other and with a model developed from flow considerations. Average void fraction versus superficial velocity curves were also compared with an available model developed from bubble rise theory.
