Small Bubbles Formation and Contribution to the Overall Gas Holdup in Large Diameter Columns of Very High Viscosity Oil (2022)
Journal Article

A limited number of studies are available in literature on the small bubbles which create from gas-very high viscosity oils interaction and its contribution to the gas holdup in the system. The rate of small bubble formation has an important impact o...

An experimental study on the effect of gas injection configuration on flow characteristics in high viscosity oil columns (2021)
Journal Article

Gas-viscous liquid bubbly and slug flow are very common in petroleum, chemical, bioengineering, polymer, and food processing. However, there is a major knowledge gap in two-phase flow research in the design of gas injectors/distributers in very high...

Evaluation of Microwave Applicator Design on Electromagnetic Field Distribution and Heating Pattern of Cooked Peeled Shrimp (2021)
Journal Article

Non-uniform temperature distribution within solid food is a major problem associated with microwave heating, which limits industrial applications. Therefore, an experimentally validated 3D model was proposed to study the effect of microwave applicato...

Effects of the heating source on the regeneration performance of different adsorbents under post-combustion carbon capture cyclic operations. A comparative analysis (2021)
Journal Article

This work presents a comparative study of microwave and conventional (conductive) heating for adsorbent regeneration. A binary gas mixture representative of pre-dried flue gas from coal-fired power plants (15% v/v CO2 in N2) was passed through a rota...

Mathematical modelling of dielectric properties of food with respect to moisture content using adapted water activity equations (2021)
Journal Article

There is currently no recognised equation, or set of equations, that can be used to adequately describe moisture dependant dielectrics. This study addresses this issue so that moisture dependant dielectric properties can be directly input into drying...

Dynamics of flow transitions from bubbly to churn flow in high viscosity oils and large diameter columns (2019)
Journal Article

The dynamic behaviour of the gas-liquid two phase flows and in particular the flow pattern stability and transition between the flow regimes are influenced significantly by both the properties of the liquid and gas as well as the pipe diameter.
