Title:Heat Transfer
Long Title:Heat Transfer
Module Code:MECH8008
 
Duration:1 Semester
Credits: 5
NFQ Level:Advanced
Field of Study: Mechanical Engineering
Valid From: Semester 1 - 2016/17 ( September 2016 )
Module Delivered in 2 programme(s)
Module Coordinator: GER KELLY
Module Author: GER KELLY
Module Description: This module is designed to give the student an in-depth understanding of all heat transfer mechanisms viz. conduction (transient and steady state); convection (free and forced); and radiation, coupled with an introduction to and the application of Computational Fluid Dynamics Techniques to classical heat transfer problems.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Apply the conduction equation in rectangular, cylindrical or spherical coordinates 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 Analyse the construction, materials and performance of solar collectors.
LO4 Analyse heat transfer problems using Computational Fluids Dynamics Methods
Pre-requisite learning
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 CIT 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.
