Course Description

This course follows a unified approach to introduce the physical origins and rate equations of heat and mass transfer. The principal topics covered include identification of the driving forces for heat and mass diffusion, development of transport models from first principles, steady state and transient solutions, and convective transfer. The boundary layer analogies are introduced. Closed form analytical solutions and correlations derived from dimensional analysis are used to estimate the heat and mass transfer convection coefficients. (0/0/0/42/0)

Objectives and Outcomes

The principal objective of the course is to provide the necessary tools to help engineers design and operate processes and unit operations in chemical engineering and engineering chemistry. The students will learn how to identify the fundamental heat and mass transfer mechanisms. The course will teach the concepts and methodology needed to develop mass and energy balances and to simplify them and obtain solutions that are applicable to real problems.

Specific course learning outcomes include:

  1. Identification of mechanisms of heat and mass transfer. Formulation of rate equations.
  2. Development of transport models based on the differential equations of heat and mass transfer and their simplified forms; identification of suitable boundary conditions.
  3. Solutions of the differential equations for steady-state, one-dimensional problems; solutions for non-steady state problems.
  4. Estimation of heat and mass transfer coefficients based on dimensional analysis, boundary layer analysis and similarity between momentum, heat and mass transfer.
  5. Solution of problems involving  convective heat and mass transfer in one phase and two phase systems

Relevance to the Program

This engineering science course covers aspects of heat and mass transfer, which together with fluid mechanics comprise one of the corner stones of chemical engineering and engineering chemistry, the so-called "transport courses". The engineering science skills taught in this course are required for 3rd year courses (CHEE 331/332/333 – Design and scale-up of unit operations, CHEE 323 – Industrial catalysis) and 4th year courses (CHEE 412-Transport Phenomena in Chemical Engineering, CHEE 470-Design of Manufacturing processes, CHEE 442 – Introduction to biomedical engineering).

The course assumes knowledge of 2nd year fluid mechanics and thermodynamics.
