MEng Chemical Engineering / Course details

Year of entry: 2021

Course unit details:
Momentum, Heat & Mass Transfer

Unit code CHEN20112
Credit rating 10
Unit level Level 2
Teaching period(s) Semester 2
Offered by Department of Chemical Engineering & Analytical Science
Available as a free choice unit? No

Overview

The unit is broken up into 6 parts. The introduction provides a basic review for fundamentals prerequisites to the module including vector and tensors, general balances, and dimensional analysis. The next 3 parts cover momentum, mass, and energy transport. In each of these sections is covered the corresponding mechanisms for diffusive transport (Newton’s law, Fick’s law, Fourier’s law) and the generation terms. The generalized transport equations (including the Navier Stokes equation) are derived from shell balances. Example problems are given in each section demonstrating the application of shell balances to solve transport problems. The last two section cover turbulence and analogies in momentum, heat, and mass transfer.

Aims

The unit aims to: To advance the knowledge of momentum, heat and mass transfer as covered in CHEN 10031 and CHEN 10092 to obtain a fuller, more comprehensive understanding of these fundamental concepts, principles and analytical techniques related to transport phenomena in a unified and quantitative manner.

 

Learning outcomes

Students will be able to:

1.Perform scalar, vectorial and tensorial calculations in momentum balances.

2.Recognize and use the laws for diffusive transport.

3.Apply the Navier Stokes equations and Newton’s law of viscosity to derive velocity profiles under laminar flow.

4.Derive temperature and mole fraction profiles from their relevant differential balances and laws.

5.Apply dimensional analysis to simplify transport problems, interpret their solutions and generalize the results.

6.Describe the meaning of dimensionless numbers relevant for transport phenomena.
