Summary
This module provides a bridge between heat, mass and momentum transport in a number of industrial and environmental systems. The core of the module is to demonstrate the interdependency of these three and how to analyse such systems to solve practical problems that arise in the industry. A simple yet powerful CFD package is used to simulate certain transport problems with appropriate guidance and therefore a prior knowledge of CFD is not necessary. The main topics covered in this module are:
- Conservation laws: Basic heat mass and momentum transport equations.
- Dimensional analysis and similarity solutions.
- Modelling flows: Problem simplification assumptions and boundary conditions.
- Mixing flows: turbulence and effect on heat and mass transfer.
- Boundary layers: Boundary layer theory and diffusion limited processes.
- Basics of CFD: Concepts of discretisation, meshing and good practices.
- Applications of heat mass and momentum transfer: microfluidics, thin film flows, plumes and spread of pollutants, mixing tanks and reactors, double diffusion in LNG tanks.

Educational Aims
The module aims to provide an in depth knowledge of heat, mass and momentum transport that is necessary in assessing, analysing and developing chemical, biochemical and environmental processes. Furthermore, this module fills the gap between first year transport phenomena and the fourth year CFD module while introducing the multiphysics aspect of the discipline. The module will cover advance topics in heat, mass and momentum transport providing descriptive explanations together with essential mathematical tools. The interdependency of heat, mass and momentum transport will be presented with real world examples such as drying, evaporating films and double diffusion in chemical storage tanks.Learning Outcomes
A2 Chemical Engineering Principles:
A2.1.5 Different time scales: short and long periods steady and unsteady state. Demonstrated by the ability to make evidence-based assumptions when solving transport phenomena problems. As evidenced by exam question and coursework on diffusional/convective time scales and steady/transient state.
A2.2.2 Understand the principles of momentum, heat and mass transfer, and application to problems involving flowing fluids and multiple phases. Demonstrated by the ability to formulate and apply simplified first-principles models to the transport of moment, heat and mass. As evidenced by exam questions.
A2.2.6 Be able to apply the same underlying principles to more complex problems, critically evaluating the limitations of assumptions of the approach taken. Demonstrated by the ability to formulate and apply simplified first-principles models to the conjugate transport of moment, heat and mass. As evidenced by exam questions.
A2.3.3 Be able to select and adapt computational and analytical techniques to tackle complex problems. Demonstrated by the ability to use conventional Excel functions to solve discretised transport models (e.g. MInv and MMult functions) or VBA/Python coding. As evidenced by coursework and exam questions that requires the student to solve transient and two-dimensional transport phenomena problems.
A5 Embedded Learning:
A5.2.1 Have developed a wide range of problem-solving skills. Demonstrated by the ability to identify and clarify problems, assumptions and constraints, to reflect on possible solutions, to plan a solution procedure, to gather quality evidence, to make evidence-informed decisions, and to communicate solutions.
