Bubble and cavitation effects phenomena can be encountered in two-phase gas-liquid systems in industry. In certain industries, particularly high-risk systems such as a nuclear reactor/plant, the detection of bubble dynamics, and the monitoring and measurement of their characteri…
A method of measuring the moan liquid velocity in an airwater two-phase flow has been successfully developed utilising an electrolyte tracer technique. Liquid holdup is derived from this velocity measurement and compared with existing correlation. Two new liquid holdup correlati…
The objective of this thesis was to develop a novel understanding of the mechanics of two phase gas-liquid flows and sprays injected through industrial effervescent nozzles. This was done using detailed experimental investigations and scaling for two-phase flows and sprays. This…
Developing a landfill model is essential to understanding how the landfill gases are generated, and migrate. In this Thesis, four different aspects of landfill modeling are studied, in order to design a realistic model for a landfill, and an efficient landfill numerical simulato…
Liquid-solid slurry flows are important to many industrial processes such as coal-water transportation, heterogeneous reactors, mining industry, ash transportation, transfer of process slurries in chemical plants, and Biological flows. Although solid-liquid slurry flow has been …
The residence time and residence-time distribution (RTD) of fresh and simulated particles flowing in a swept surface heat exchanger (SSHE) and holding tube were investigated. The effects of selected experimental conditions on RTD include particle shape (cube, cylinder, and spher…
Two and three-phase flow processes involving gas, liquid and solid, are common in nature and industry, and include some of the most complex and poorly-understood transport problems. In this research hydrodynamics, heat and mass transfer processes in complex two and three-phase f…
