Module Overview 
This module gives a solid grounding in the aspects of heat transfer that are essential for Chemical Engineers. It covers fundamental transfer mechanisms and both transient and steady state problems. Heat exchanger design and performance calculations are thoroughly addressed, as are pipe flow problems and heat transfer coefficient evaluation. Simple radiation exchange problems are introduced. 


Prerequisites/Corequisites 
Normal entry requirements for degree programmes in Systems Engineering 


Module Aims 
Most chemical and process engineering operations include the transfer of heat. This module will;
a) familiarise students with the mechanisms of heat transfer and with the basic approach to solving steady state and transient heat transfer problems
b) Teach performance and design calculation methods for a range of heat exchanger types.
c) Introduce heat flux calculations for conduction, convection and radiation transfer mechanisms
d) Analyse heat transfer in pipe flow




Learning Outcomes 
Upon successful completion of the module you will be able to:
· Appreciate the significance of heat transfer in chemical engineering
· Understand and describe the different mechanisms of heat transfer
· Solve simple transient problems
· Solve1dimensional conduction problems through multiple layers in plane and cylindrical geometries.
· Solve heat exchanger performance and design problems
· Appreciate the parameters that influence overall heat transfer coefficients, and determine the same from suitable correlations
· Analyse and solve axial temperature distribution for pipe flow.
· Describe the key concepts of radiative heat transfer and perform simple radiation exchange calculations.
