Aims

This module reinforces and adds to the knowledge of heat transfer and fluid mechanics gained in Stage 1. The study of heat transfer is extended to systems which are no longer steady state and have changes in phase. Heat exchanger design is greatly extended from the simple counter and cocurrent designs to numerous designs. Radiative heat transfer is introduced. The fluid mechanics of pumps are studied in detail, and again the course extends the knowledge to analyse new types of fluids and flow, including gas flows and flows containing multiple phases.

1. Fluid Mechanics:
CME1023 provided a fundamental understanding of fluid flow and properties. This course aims to generalise fluid mechanics so that at a later stage, the knowledge gained can easily be used in numerical simulations, such that the students understand the meaning and implications of exact/approximate solutions in the description of fluids, flow geometry and flow kinematics. Governing fluid flow equations, including the equations of state, are obtained in 3D form in tensor notation and applied to the flow of Newtonian and non-Newtonian fluid flows in simple geometries. More complex fluid systems such as compressible and multi-phase fluids are also examined and related to the process industries.

2. Heat Transfer:
i. To extend the knowledge of the principles of heat transfer gained in CME1023 and to provide a fundamental knowledge of design criteria for typical forms of heat exchangers used in the process industries.
ii. To enable the students to analyse heat transfer in systems where there is change of phase.
iii. To introduce and analyse transient heat transfer.
iv. To allow the students to analyse systems where radiative heat transfer is significant/dominant.
v. To ensure that students can design and choose appropriate equipment in their design projects.

Teaching Rationale And Relationship

Lectures convey the mathematical concepts and techniques in fluid mechanics and heat transfer; tutorials are used to provide supervised problem solving; workshops are used to provide support during the open-ended design case study assignment, and additional time is reserved for independent study, for literature and digital sources research, and for assessment preparation.

Report1M25Transfer Processes assignment. Open-ended design problem - fluid flow and heat transfer.
Assessment Rationale And Relationship

The invigilated written exam will test both the fluids and heat transfer content studying in this module, containing a mixture of calculation-based questions, and critical evaluation questions (AHEP4 1-3,5,13).

The transfer processes assignment assesses the students’ ability to combine their knowledge of heat transfer and fluid flow to a chemical engineering open-ended design problem, making use of extended literature and digital sources research, and practicing report writing skills (AHEP4 1-6, 12, 13, 17).
