Designing a gas turbine requires a team work of several groups that are specialized in aero-thermodynamics, heat transfer, computational fluid dynamics, combustion, solid
1. Introduction. A gas turbine, also called a Com bustion Turbine, is a type of internal combustion. engine. It has an upstream rotating compressor coupled to a downstream rotating. turbine and in
The advent of gas turbines with ratings of well over 100 MW, combined with steam turbines, provided very high thermal efficiencies and large capacity systems, allowing the

Design of gas turbines was from very beginning based on sound physics rather than empiricism. The first gas turbine manufactured around 1900 was not even able to rotate, because the turbine power was much less than the required compressor power. The
The sequential combustion technol-ogy employed by in the GT24 and GT26 gas turbines allows a thermal effi-ciency of 38 percent to be achieved, with the prospect of 40 percent in the near future without having to significantly. plant. Low gas inlet temperature, relatively low cooling-air consumption.
This paper aims at modeling a gas turbine blade which works at super-critical operating conditions using the alloys Ti-6Al-4V and the Alloy 1.2367. The results obtained after the simulation
This book written by a world-renowned expert with more than forty years of active gas turbine R&D experience comprehensively treats the design of gas turbine
Gas turbines that produce shaft power are power generation gas turbines. Gas turbines that convert the fuel energy into kinetic energy are used for generation of thrust to propel aircrafts. The conversion of fuel energy into shaft power or propulsive force, requires interaction of several components of the engine, within each of
Any preliminary design procedure must make assumptions about a number of critical parameters which must be refined as the design progresses through its various stages. Firstly, the designer has to specify the geometry of the turbine together with any assumptions about losses from which to calculate an efficiency value.
Blade fatigue is a major source of failure in steam turbines and gas turbines. Fatigue is caused by the stress induced by vibration and resonance within the operating range of machinery. To protect blades from these high dynamic stresses, friction Fig 1.
Based on the structure, application, and the output power (MW), gas turbines can be classified into five main groups (Boyce 2006) including: Micro power. gas turbines (MGTs), with 20-350 KW output. Small gas turbines for simple cycle applications, with 0.5-2.5 MW output power and 15-25% efficiency.
Compressor and turbine maps are both required for modelling off-design behaviour of gas turbine systems accurately. Their efficiency at part-load affects the thermal efficiency (and thus specific
