Module Details

Module Code: MECH8008
Title: Heat Transfer
Long Title: Heat Transfer
NFQ Level: Advanced
Valid From: Semester 1 - 2024/25 ( September 2024 )
Duration: 1 Semester
Credits: 5
Field of Study: 5211 - Mechanical Engineering
Module Delivered in: 2 programme(s)
Module Description: This module is designed to give the student an in-depth understanding of the heat transfer mechanisms of conduction (transient and steady state), convection (free and forced) and radiation.
 
Learning Outcomes
On successful completion of this module the learner will be able to:
# Learning Outcome Description
LO1 Apply conduction models for heat transfer to problems in transient and/or steady state conduction
LO2 Develop representative models of laminar/turbulent, internal/external, free/forced convection problems and their solutions.
LO3 Apply appropriate models of conductive/convective/radiative heat transfer to heat transfer equipment.
LO4 Critically review solutions to heat transfer problems with respect to the assumptions and limitations of models used in the solutions.

Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
None
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
None
Co-requisite Modules
No Co-requisite modules listed
Requirements

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
