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 define and quantify conductive (one- and two-dimensional steady state conduction, transient conduction), convective (free, forced and phase change) and radiative (radiation properties and shape factors) heat transfers.
Learning is assisted by analysing practical, discipline specific applications such as plane walls, radiators and underfloor heating; domestic and industrial products such as ovens and heat exchangers; and laboratory practicals involving temperature, heat transfer and thermal property measurement.
Further context is provided by highlighting how heat transfers (thermal energy and efficiency) underpin ethical considerations such as 'health and safety' and 'sustainable development', emphasised in both Engineers Ireland's Code of Ethics and relevant UN's Sustainable Development Goals (SDGs).
Learning Outcomes
Describe the empirical laws and physical mechanisms that define the three modes of heat transfer: conduction, convection and radiation.
Select the appropriate empirical law(s) or problem-solving technique required in different contexts or applications.
Apply the appropriate conductive, convective and/or radiative heat transfer analysis in different contexts or applications.
Devise a finite difference numerical model to assist the analysis of a two-dimensional conductive heat transfer problem.
Explain the significance of the outcome(s) obtained from either theoretical calculation and/or numerical modelling.
Critique the method of analysis, outcome(s) and conclusion(s) from the ethical perspectives outlined in Engineer Ireland's Code of Ethics and relevant SDGs.
Recognise the limitations of either the theoretical calculation or numerical modelling analysis conducted.
Plan and execute an experimental program capable of validating the accuracy of the theoretical calculation or numerical modelling analysis.
