Advanced Transport Phenomena (Undergraduate Honours course)

This course aims to teach students how to think about problems in transport phenomena. Given a physical problem, students will learn how to formulate a consistent mathematical model based on first principles, and how to simplify and analyse the equations to obtain useful physical insights and make quantitative predictions. To facilitate a deeper understanding of the governing partial differential equations, the course begins with the mathematical description of flows and forces in continuum media and a careful derivation of the transport equations. The remainder of the course is dedicated to the analysis and approximate solution of these equations using a range of concepts and techniques, including order-one scaling, perturbation and averaging methods. The course is structured around model problems which will be worked through in entirety, from formulation to solution and interpretation. These case studies will illustrate various techniques in physically meaningful contexts, while demonstrating the importance of maintaining a close interplay between mathematical methods and physical understanding.
