ENGINEERING TRIPOS PART IIA - 2012/2013
Leader: Dr A Boies email: amb233
Project Type: Group
Project Category: Design
Prerequisites: 3A5 Strongly recommended.
Timing: Thursdays 11-1pm, and Mondays 9-11am plus afternoons
The past two decades have seen a technical revolution in the power generation industry. This has been driven by rapid developments in gas turbine technology, the large-scale use worldwide of natural gas as a fuel, and the increased level of awareness concerning the consequences of environmental pollution. Since the early 1990s, thermal efficiencies of the best power stations have risen from 40% to 55% and are now approaching an astonishing 60%. These very high efficiencies are usually achieved by using a gas turbine to top a steam cycle, the so-called combined-cycle power plant.
However, cycle analysis is currently an extremely active area of research, with many new and novel cycles being proposed. Examples include gas turbine cycles with water or steam injection, cycles incorporating fuel cells, and cycles exploiting coal gasification. Some of these cycles promise extremely impressive thermodynamic performance, often at considerably lower capital cost than the combined-cycle.
In this project you will in teams of three undertake a computer-based investigation of combined-cycles and some of the above-mentioned advanced cycles, using a suite of especially written computer programs. (The analysis programs are written in FORTRAN, but a knowledge of this language is not required: for the most part you will use the programs with no or little modification. Some of the visualisation programs are written in Matlab code with which you should be familiar from Part I.) Cycle analysis and design is a complex procedure requiring comparatively elaborate calculations and it is virtually impossible to perform even the simplest design-point optimisation without the help of such programs. However, the project is structured in such a fashion that you should develop a firm understanding of the thermodynamic principles that underpin the operation of power generating plant. This understanding is essential to the innovation of new power generating cycles.
