Determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. In this paper, the maximum power of the MGT-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. In a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required sta...

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...

As a result of their unique heat recovery properties, Humidified Gas Turbine (HGT) cycles have the potential to deliver resource-effective energy to society. The Evaporative Gas Turbine (EvGT) Consortium in Sweden has been studying these types of cycles for nearly a decade, but now stands at a crossroads, with commercial demonstration remaining. This thesis binds together several key elements f...

Over the last 50 years industrial gas turbines have advanced significantly. Horsepower has increased 200 percent (and even higher) within the same envelope. Improvements in efficiencies and reliability (more operating time before overhauls) are being made more often. What took 15 years to change 30 years ago, now, in the last 15 years, happens in five years or less. There are constant demands f...

Measurements of the flow field around a low pressure turbine blade are presented. The purpose of the experimental study is to investigate the detailed transition and separation characteristics on low pressure turbine blades. The present study focuses on the effect of Reynolds number on the formation of separation bubbles on the turbine blade surface. Specific attention is paid to the flow withi...

Gas turbines can be exposed to microparticle ingestion throughout their lifespan due to the harsh conditions, like deserts, in which many of them operate. Microparticles can wear out turbine blades and clog cooling holes which may result in the failure of the blade. To measure the interaction of microparticles with turbine components the Coefficient of Restitution (COR) is used. The objective o...

This paper presents PID controller designs based on NARMAX and feedforward neural network models of a Spey gas turbine engine. Both models represent the dynamic relationship between the fuel flow and shaft speed. Due to the engine non-linearity, a single set of PID controller parameters is not sufficient to control the gas turbine throughout the operating range. Gain-scheduling PID controllers ...

A new generation of small scale (less than 20 MWe) biomass fueled, power plants are being developed based on a gas turbine (Brayton cycle) prime mover. These power plants are expected to increase the efficiency and lower the cost of generating power from fuels such as wood. The new power plants are also expected to economically utilize annual plant growth materials (such as rice hulls, cotton g...
