About the Course:

This course aims to offer intermediate to advanced heat transfer content for students interested in fluid-thermal engineering. While most undergraduate and graduate level heat transfer courses are focused primarily on deriving accurate analytical solutions to well-posed problems, engineers often have to deal with complicated geometries with no analytical solutions. In these situations, they would have to resort to numerical solutions, which can be time and resource intensive. The goal of this course is to provide students with practice in:

  1. Exposure to various analytical tools for solving heat transfer problems.
  2. Identifying simplifying assumptions and models that can sufficiently represent real-world problems. Arriving at quick order of magnitude estimates which can help decide whether proceeding with further analysis is warranted.

Course contents:

  1. Introduction to modelling real world problems
  2. Applied dimensional analysis
  3. Resistance network models, insights
  4. Multidimensional conduction approximate solutions
  5. Transient conduction: limiting cases, approximate results
  6. Semi-infinite analysis, applications
  7. Convection: integral boundary layer analysis
  8. Radiation
