Overview

Heat transfer is a necessary process in virtually all forms of energy generation and use; from coal fired to nuclear power stations, from automobile engines to rocket motors, from refrigerating cold stores to air conditioning space vehicles. A sound knowledge of this field is essential for all mechanical engineers.

This course further develops the basic physics concepts and principles learned in thermodynamics and fluid mechanics to heat transfer in its three different modes. The three modes are conduction, convection (free and forced) and radiation. Application of these principles to practical industrial applications is an important aspect of this course.

Course learning outcomes

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. identify the various modes of heat transfer that are taking place in a particular system;
  2. analyse and design simple and complex thermofluids systems working at steady or non steady situations using analytical and numerical methods;
  3. modify existing designs to achieve high efficiency.
