Aims

• To provide knowledge of common fluid properties (e.g viscosity, density, surface tension etc.).
• To provide a fundamental knowledge of the mechanisms of fluid flow and apply this knowledge to solve fluid flow problems commonly encountered in chemical engineering processes.
• To understand and apply the techniques for flow measurement.
• To provide an introduction to mass transfer theory and phase equilibria.
• To introduce the 3 types of heat transfer.
• To enable analysis of conductive systems in various geometries and with multiple layers
• To enable analysis of convective systems, with or without conduction
• To introduce dimensional analysis, and its applications to heat transfer problems
• To introduce and enable analysis of extended surfaces
• 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 Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

Synchronous and non-synchronous Lectures convey the basic concepts of momentum, heat and mass transfer and demonstrate their application in chemical engineering context, whilst synchronous and non-synchronous . Tutorial classes support the lecture material is 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.

Alternatives will be offered to students unable to be present-in-person due to the prevailing C-19 circumstances.
Student’s should consult their individual timetable for up-to-date delivery information.

Assessment Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The quizzes in Semesters 1 and 2 examination are is an appropriate way to assess mathematical and analytical skills applied in combination with assessment of the fundamental knowledge of fluid mechanics, heat transfer and mass transfer.

Students must pass the laboratory reports.

The assignment allows more realistic open ended, engineering problems to be investigated and solved.
The lab reports allow critical analysis of real data from experiments and allow development of technical report writing skills and graphical analysis.
