ON THE COOLING OF GAS TURBINES
Journal of Flow Visualization and Image Processing, 2001This article deals with measurements of convective heat transfer coefficients in three fluid flow patterns that concern both internal and external cooling of gas turbine components; in particular, the flow in a couple of smooth, or ribbed, ducts connected by a 180° sharp turn, a jet in cross-flow, and a jet impinging on a wall for short nozzle-to-wall ...

Sono inizialmente discusse le ipotesi semplificative adottate per i successivi sviluppi termodinamici; e quindi definito il rendimento dell’eventuale scambiatore di calore, insieme a determinati fattori di perdite dello stesso; sono poi caratterizzate le trasformazioni, che si svolgono nel compressore e nella turbina, attraverso le quantita di calore ...

International Journal of Hydrogen Energy, 1986
Abstract The generation mix of Electricite de France includes a large number of nuclear power plants. This enables E.D.F. to produce cheap off-peak electricity. Therefore electrolytic hydrogen could be produced at low cost. Ammonia manufacturers and other chemical plants are potential consumers.

International Metallurgical Reviews, 1975
The major components of gas turbines and their materials requirements are outlined. The properties, advantages, and limitations of materials which have been and are being used in gas turbines are then described in the following groups: aluminium alloys, magnesium alloys, titanium and its alloys, steels, and finally nickel- and cobalt-base alloys.

Technological Forecasting and Social Change, 1999
Abstract The use of gas turbines in the electric industry of many countries has been increasing. Their demand now represents more than 50% of the world market of thermal power plants. In this article we test the paradigm concept to explain the technological change that represents the gas turbine in electricity generation.

As discussed in Chapter 2, the supercharger (basically, an air compressor) can also be driven by an exhaust gas turbine. In this case, the overall system is referred to as a turbocharger or turbosupercharger (Abgasturbolader in German). The focus in Kollmann’s manuscript is exclusively on radial compressors used as superchargers driven by a gear drive ...
