Heat Transfer

Description

This module introduces the learner to the three modes of heat transfer; conduction, convection and radiation. Attention is focused on the physical mechanisms and empirical laws used to quantify conductive (one- and two-dimensional steady state conduction, transient conduction), convective (natural/free, forced, boiling and condensation) and radiative (radiation properties and shape factors) heat transfers. Theory is supported by reference to typical applications (buildings, heat exchangers, materials, electronics) and exposure to laboratory experiments.

Learning Outcomes

  1. Describe the laws governing steady-state heat transfer by the three modes of heat transfer  (conduction, convection and radiation).

  2. Apply the heat transfer equations for solving one- and two dimensional, steady-state and transient heat transfer for both heating & cooling applications.

  3. Solve manually and numerically basic heat transfer problems by identifying the appropriate boundary and initial conditions.

  4. Identify the dominant heat transfer modes that relate to different problems/situations, discern what assumptions apply to the theoretical examinations, or what sensors or experimental study is required to validate either the theoretical approach, the assumptions made or both.

  5. Perform fundamental conductive heat transfer experiments and use the information to validate theoretical calculations.

  6. Demonstrate an understanding of the different forms of convective heat transfer (Natural/Free, Forced and Boiling and Condensation).

  7. Demonstrate an understanding of the complex interactions between the fluid motion, the object geometry and the thermo-physical properties that give rise to a wide range of empirical heat transfer correlations.

  8. Select the appropriate empirical heat transfer correlations considering the appropriate boundary and initial conditions correlations to solve fundamental and practical heat transfer problems.   

  9. Apply the appropriate empirical heat transfer correlation to solve fundamental and practical heat transfer problems.

  10. Perform fundamental convective heat transfer experiments and use the information to validate 'theoretical' calculations.

  11. Demonstrate an understanding for the physical mechanisms and empirical laws used to describe and quantify radiation heat transfer rates.

  12. Perform fundamental radiative heat transfer experiments and use the information to validate 'theoretical' calculations.
