• To understand Reynolds analogy for heat transfer
• To introduce dimensional analysis, and its applications to heat transfer problems
• To introduce and enable analysis of extended surfaces
• To introduce radiative heat transfer
• To enable the students to design simple heat exchangers
To provide an introduction to mass transfer theory and phase equilibria.

This module teaches the fundamentals of momentum, heat and mass transfer processes.

Momentum transfer or fluid flow is one of the most important processes in chemical engineering. This module will provide students with fundamental knowledge for solving common chemical engineering flow problems. It will build on knowledge of fluid flow properties to introduce the concept of Reynolds number, frictional pressure drop and mechanical energy balances.

This module introduces the 3 basic types of heat transfer: conduction, convection and radiation. By the end of the module the students will be able to understand many everyday examples of heat transfer, as well as being able to solve many steady state heat transfer calculations that Chemical Engineers encounter on plant.

The module will explain the processes of mass transfer and diffusion and apply them to engineering systems of separation and reactions. These principles build on knowledge of fluid behaviour and the analogy between momentum; heat and mass transfer.

Teaching Rationale And Relationship

Lectures convey the basic concepts of momentum, heat and mass transfer and demonstrate their application in chemical engineering context. Tutorial classes support this through extended examples. Practical sessions allow theoretical principles developed in lectures to be applied in hands-on experiments to more effectively aid understanding and assimilation of material.

Assessment Rationale And Relationship

The examination is an appropriate way to assess mathematical and analytical skills in combination with the fundamental knowledge. Students must pass the laboratory reports.

The assignment allows more realistic open ended, engineering problems to be investigated and solved.
