# BEng Chemical Engineering

Year of entry: 2024

## Course unit details:Momentum, Heat & Mass Transfer

Unit code CHEN20112 10 Level 2 Semester 2 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.

### Pre/co-requisites

Unit title Unit code Requirement type Description
Engineering Mathematics 1 CHEN10011 Pre-Requisite Compulsory
Process Fluid Flow CHEN10031 Pre-Requisite Compulsory
Process Heat Transfer CHEN10092 Pre-Requisite Compulsory
Engineering Mathematics 3 CHEN20041 Pre-Requisite Compulsory

### 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

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

ILO 2: Recognize and use the laws for diffusive transport.

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

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

ILO :5 Understand the concept of material versus substantial derivative.

ILO :6 Apply dimensional analysis to simplify transport problems, interpret their solutions and generalize the results

ILO : 7 Describe the meaning of dimensionless numbers relevant for transport phenomena.

### Teaching and learning methods

Lectures provide fundamental aspects supporting the critical learning of the module and will be delivered as pre-recorded asynchronous short videos via our virtual learning environment.

Synchronous sessions will support the lecture material with Q&A and problem-solving sessions where you can apply the new concepts. Surgery hours are also available for drop-in support.

Feedback on problems and examples, feedback on coursework and exams, and model answers will also be provided through the virtual learning environment. A discussion board provides an opportunity to discuss topics related to the material presented in the module.

Students are expected to expand the concepts presented in the session and online by additional reading (suggested in the Online Reading List) in order to consolidate their learning process and further stimulate their interest to the module.

Study budget:

• Core Learning Material (e.g. recorded lectures, problem solving sessions): 24 hours
• Self-Guided Work (e.g. continuous assessment, extra problems, reading)     : 44 hours
• Exam Style Assessment Revision and Preparation: 32 hours

### Assessment methods

 Assessment Types Total Weighting Mid-semester exam style assessment 20% Final Exam 80%

Please note that the exam style assessments weighting may be split over midterm and end of semester exams.
