DESIGN OF TESLA TURBINE Abstract:- The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The Tesla turbine is also known as the boundary layer turbine‚ cohesion-type turbine‚ and Prandtl layer turbine (after Ludwig Prandtl). Bioengineering researchers have referred

Steam Turbines The invention of the water turbine was so successful that eventually‚ the idea came about for extracting power from steam. Steam has one great advantage over water-it expands in volume with tremendous velocity. To be the most effective‚ a steam turbine must run at a very high speed. No wheel made can revolve at any speed approaching the velocity that a steam turbine can. By utilizing the kinetic energy of steam flow‚ the turbine could achieve a higher efficiency. As a result

Introduction to Gas Turbines A turbine is any kind of spinning device that uses the action of a fluid to produce work. Typical fluids are: air‚ wind‚ water‚ steam and helium. Windmills and hydroelectric dams have used turbine action for decades to turn the core of an electrical generator to produce power for both industrial and residential consumption. Simpler turbines are much older‚ with the first known appearance dating to the time of ancient Greece. In the history of energy conversion‚ however

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush‚ who ran his entire Euclid Avenue mansion off of one for 20 years‚ which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn’t rise a great deal afterwards‚ this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose

HYDRAULIC TURBINES Meaning of the term ‘Hydraulic’ • The working fluid is a liquid or a gas?? ANSWER – WORKING FLUID IS A LIQUID. TURBINE – WORKING PRINCIPLE • In turbines the pressure energy is converted into mechanical energy(which is further converted into electrical energy). WORKING PRINCIPLE OF PUMPS it is just the reverse of the above‚ that is‚ the mechanical energy is converted into pressure energy. OUR FOCUS OF STUDY • Working of various types of hydraulic turbines. • Working
