Courses

Doctoral thesis proposal development based on technical writing process, data interpretation, experimental design. Students who successfully complete the course will be able to assess information from the primary scientific literature, formulate scientific questions (hypotheses), and generate an experimental plan to help validate or nullify their hypothesis. Students will demonstrate a command of oral and written communication skills by completing this course.

Investigations of a fundamental and/or applied nature representing an original contribution to the scholarly research literature of the field. PhD dissertations are often published in refereed journals or presented at major conferences. A written dissertation must be completed in accordance with the rules of the Graduate School and the College of Engineering. Admission to the course is based on successful completion of the PhD comprehensive examination and submission of a formal proposal endorsed by the student's graduate committee and submitted to the EAS Graduate Program Director.

Mechanical Engineering applications of Thermodynamics, Fluid Dynamics, and Heat Transfer. The design and operation of thermal engineering systems and components, including heat exchangers, thermal engines and refrigeration systems are considered from the combined mechanics of materials, heat transfer, fluid dynamic and thermodynamic point of view. Design optimization of components to minimize energy destruction/entropy generation are studied along with economic considerations. The course includes a thermal design project.

Ocean Wave Energy Conversion

Visiting professors or members of the faculty present current topics of interest in their areas of expertise.

Fundamentals of heat transfer in fluid flows undergoing phase change. Thermodynamic equilibrium and stability during boiling/condensation is taught. Nucleation and bubble growth in homogeneous and heterogeneous regimes are presented. Distinct flow patterns and heat transfer characteristics in two-phase, boiling flows are discussed. Heat transfer in pool boiling and condensation is presented. Liquid-solid phase change is taught at an introductory level.

Mehdi Raessi joined the Mechanical Engineering Department in 2010 following a postdoctoral study at NASA-Stanford University's Center for Turbulence Research (CTR). He obtained his PhD in Mechanical Engineering from the University of Toronto in 2008. During his graduate studies, he worked in the Centre for Advanced Coating Technologies (CACT).

Dr. Raessi's research is primarily focused on numerical simulations of interfacial flows and two-phase flows with phase change. Using numerical simulations, he has been studying the fluid flow and heat transfer in various applications including energy systems (renewable and conventional), materials processing, and environmentally friendly refrigeration systems. In addition to academic research and teaching, Dr. Raessi has industrial experience as a research and development (R&D) specialist and applied engineer.
