Michaelmas term. 75% exam / 25% coursework. 12 lectures (including examples classes) + coursework
Prerequisites
3A1 and 3A3 assumed
Aims
The aims of the course are to:
- provide a general understanding of the principles that govern the design of axial flow and radial flow turbomachines.
Objectives
As specific objectives, by the end of the course students should be able to:
- understand the principles underpinning the study of turbomachine aerodynamics.
- know the requirements for different type of turbomachines.
- know the factors which influence the overall design of turbomachine stages and which influence the matching of components.
- know the factors which influence overall design of turbomachines for propulsion and stationary power-plant applications.
- evaluate the performance of turbine and compressor bladerows and stages using mean-line analyses.
- select a design for a given duty.
- present and understand information on stage and machine design.
- describe and understand compressor off-design performance.
- analyse the performance of propulsion systems and stationary power plant.
Content
Applications and Characteristics of Turbomachines (12L, Prof. RJ Miller and Dr J. Taylor)
