Micro turbines are becoming widespread for distributed power and combined heat and power applications. They are one of the most promising technologies for powering hybrid electric vehicles. They range from hand held units producing less than a kilowatt, to commercial sized systems that produce tens or hundreds of kilowatts.Part of their success is due to advances in electronics, which allows unattended operation and interfacing with the commercial power grid. Electronic power switching technology eliminates the need for the generator to be syn ....etc

Design and Performance of a Gas-Turbine Engine from an Automobile Turbocharger




Introduction

The Massachusetts Institute of Technology Department of Mechanical Engineering teaches
thermodynamics and fluid mechanics through a pair of classes, Thermal Fluids Engineering
I & II. The courses cover the basic principles of thermodynamics, fluid mechanics, and heat
transfer. This includes the rate processes involved with heat and work transfer, steady flow

A technique for on-line detection of incipient faults in the windings of turbine - generator rotors has been developed based on the twin signal sensing method. To detect the developing shorts in any winding, two identical pulses are applied to both ends f the winding and are reflected back .Any abnormality in the winding results in the applied signals being reflected through nonsymmetrical circuits. The difference between the reflected signals are amplified and used as signature signal for further processing. This paper describes the developmen ....etc

The gas turbine has been an enormously successful power plant for aircraft and marine propulsion, and electric power generation, due to its lightweight, smooth and reliable operation, low emissions, and varied applications. Nevertheless, it is not very efficient in converting fuel energy to useful work, due to fundamental thermodynamic limitations imposed by turbo machinery technology.

In recent years, there is renewed interest in the potential high efficiency of alternative thermodynamic cycles and unsteady combustion systems for propul ....etc

ABSTRACT
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 gin trash, nut shells, and various straws,
grasses, and animal manures) that are not normally considered as fuel for power plants.
This p ....etc
