A detailed experimental investigation of a perforated heat transfer surface applied to gas turbine recuperators

Autor: James Ian Oswald, Peter T. Ireland, Juan C. Adams, Martin Cerza

An effort is made to explain and improve the understanding of the mechanisms behind the thermo-hydraulic performance of perforated extended surfaces used in compact heat exchangers in the laminar flow regime (ReD = 400–2500). A transient liquid cry

Photographs on the effect of perforations on the heat transfer due to laminar flow over an extended surface

Autor: James Ian Oswald, J. C. Adams, Martin Cerza, Peter T. Ireland

In the past it has not been resolved as to whether perforated surfaces on a fin enhance heat transfer. In this photographic study which utilizes liquid crystal thermography, the evidence suggests that there is an incresse in the local heat transfer c

Will British weather provide reliable electricity?

Autor: Mike Raine, James Ian Oswald, Hezlin Ashraf-Ball

Publikováno v: Energy Policy. 36:3212-3225

There has been much academic debate on the ability of wind to provide a reliable electricity supply. The model presented here calculates the hourly power delivery of 25 GW of wind turbines distributed across Britain's grid, and assesses power deliver

Hypnotics and sleep physiology: A consensus repot

Autor: Odile Benoit, Aleander A. Borbély, Torbjörn Åkerstedt, Ian Oswald, Florian Holsboer

Publikováno v: European Archives of Psychiatry and Clinical Neuroscience. 241:13-21

The effects of hypnotics on descriptive and functional aspects of electrophysiological sleep parameters are assessed in this report. Because of the arbitrary definition of some of the criteria underlying the conventional sleep stage scoring procedure

A New Durable Gas Turbine Recuperator

Autor: James Ian Oswald, Lee A. Clawley, David Anthony Dawson

Publikováno v: Volume 2: Coal, Biomass and Alternative Fuels; Combustion and Fuels; Oil and Gas Applications; Cycle Innovations.

A new recuperator has been developed at Rolls-Royce, specifically designed to address the problems recuperators traditionally experience in withstanding thermal cycling and high cost associated with production complexity. Unlike existing recuperators

The Westinghouse/Rolls-Royce WR-21 Gas Turbine Variable Area Power Turbine Design

Autor: David Hutchinson, John C. Cox, James Ian Oswald

Publikováno v: Volume 2: Aircraft Engine; Marine; Microturbines and Small Turbomachinery.

The Westinghouse/Rolls-Royce WR-21 marine gas turbine with an intercooled, recuperated thermodynamic cycle utilises exhaust heat to provide excellent efficiency not only at full power but also at part power. Vital to the success of the engine and the
