Effect of geometrical characteristics input device gas turbine engine parameters on current

Gas Turbine Engine Behavioral Modeling

This paper develops and validates a power flow behavioral model of a gas turbine engine with a gas generator and free power turbine. “Simple” mathematical expressions to describe the engine’s power flow are derived from an understanding of basic thermodynamic and mechanical interactions taking place within the engine. The engine behavioral model presented is suitable for developing a supervisor...

Investigation of the effect of piston geometrical parameters on RCCI engine performance based on second law of thermodynamic

The reactivity controlled compression ignition engines have high thermal efficiency and low exhaust emission of nitrogen oxides and soot because of low temperature combustion. In this type of engines, low reactivity fuel is injected to air through intake port and high reactivity fuel is injected into the combustion chamber during compression stroke. The aim of current study is to investigate th...

Titanium in the Gas Turbine Engine

Gas-Dynamic Modeling of Gas Turbine Engine Components Collaborative Workflow

The aim of this article was the development of the gas-dynamic models allowing to calculate the working processes of the gas turbine engine (GTE) in the compressor, in the combustion chamber and in the turbine at the same time. The possibilities of software systems for complex engine workflow modeling are specified. The advantages and disadvantages of the presented methods are specified. The re...

Effect of Engine Operating Parameters and Fuel Characteristics on Diesel Engine Emissions

To examine the effects of using synthetic Fischer-Tropsch (FT) diesel fuel in a modern compression ignition engine, experiments were conducted on a MY 2002 Cummins 5.9 L diesel engine outfitted with high pressure, common rail fuel injection, a variable geometry turbo charger, cooled EGR and a fully configurable engine management computer. Additionally, the effect of varied injection timing and ...
