Thermal processes are crucial to the operation of many Mechanical and also Aerospace Engineering systems, such as nuclear reactors, gas-turbines, domestic heating systems, cooling of electronics and electrical components and many others. The level 3 unit on Heat Transfer, the prerequisite to this one, provides an introduction to the three modes of heat transfer, heat conduction heat convection and thermal radiation. Here the objective is to first take an in-depth look at the phenomena of forced and natural heat convection, then to introduce the topics of mass transfer, boiling and condensation heat transfer and finally to consider advanced thermal radiation topics. Coverage of these fundamental topics provides the knowledge and understanding needed to deal with the range of applications listed above. The course is delivered as 30 hours of lectures, 6 hours of examples classes, one 3-hour lab and an on-line multiple choice test.

This course unit detail provides the framework for delivery in 20/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates
