Misheck Mwaba is a postdoctoral research fellow in the Department of Mechanical and Aerospace Engineering at Carleton University. He read for a Bachelor of Engineering at the University of Zambia. He obtained his Masters of Science degree in Engineering Solid Mechanics in 1992 from UMIST in the United Kingdom. His thesis was on modeling thermal stresses in solidifying melts. For his PhD work, he investigated the problem of fouling in heat exchangers employing both experimental and numerical methods. His PhD. degree was conferred in 2003 by the Eindhoven University of Technology.
His current research interests are in the general area of energy technology. He is currently involved in the following projects:
- Fouling
The interest in this area lies in seeking effective ways of minimizing/preventing deposit formations on heat transfer surfaces. At present he is involved in experimental and theoretical research aimed at understanding the mechanisms involved in magnetic based anti-fouling devices.
- Heat Pipes
Heat Pipes are passive heat transfer devices capable of transferring high heat fluxes at low temperature differences. The present research interest is in modeling and simulation transport in porous wicks. The main objective is to gain a better understanding of boiling in wicks, and ultimately lead to design of wicks that can sustain nucleate boiling and delay commencement of film boiling.
- Fuel Cells
In this area, the research project focuses seeking ways of optimizing fuel cell performance through modeling and simulation of transport phenomena in PEM and Direct Methanol Fuel Cells.
