A Pelton wheel‚ also called a Pelton turbine‚ is one of the most efficient types of water turbines. It was invented by Lester Allan Pelton (1829-1908) in the 1870s‚ and is an impulse machine‚ meaning that it uses Newton’s second law to extract energy from a jet of fluid.

CHAPTER 1 INTRODUCTION 1.1 GENERAL Steam Turbine is a type of turbo machine. Turbo machine are those devices in which energy is transferred either to or from‚ a continuously flowing fluid by the dynamic action of one or more moving blade rows. In steam turbine energy is transferred from fluid to blade rows and is decreasing along the flow directions. It is power producing thermodynamics device. Steam turbine converts heat energy of steam (at high pressure and temperature) into mechanical

Making Water Turbines Most Energy Efficient How does a wind turbine’s output vary with wind pressure (height of water)‚ the flow rate‚ size of the motor‚ and type of blade? Introduction There are many types of energy used today: Fossil fuels‚ coal‚ nuclear energy‚ solar energy‚ geothermal energy‚ hydrogen energy‚ hydroelectric energy‚ wind energy‚ and biofuels and biomass. Non-renewable energy sources such as fossil fuels and coal are diminishing since it cannot be recycled‚ unlike wind energy

Gas Compressor Brief Introduction A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible‚ the compressor also reduces the volume of a gas. Liquids are relatively incompressible‚ so the main action of a pump is to pressurize and transport liquids. Types of Compressors Centrifugal compressors Centrifugal

for large-scale offshore floating wind turbines was introduced by Professor William E. Heronemus at the University of Massachusetts in 1972‚ but it was not until the mid 1990’s‚ after the commercial wind industry was well established‚ that the topic was taken up again by the mainstream research community. Current fixed-bottom technology has seen limited deployment to water depths of 20 m. As the technology is advanced into deeper water‚ floating wind turbine platforms maybe the most economical means

A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. 1.Steam Turbines 2. Wind Turbines 3. Water Turbines 4. Gas Turbines It is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency through the use of multiple stages in the expansion of the steam
