Challenging the Versatility of the Tesla Turbine
CORE Metadata, citation and similar papers at core.ac.uk Provided by ASU Digital Repository Challenging the Versatility of the Tesla Turbine: Working Fluid Variations and Turbine Performance by Aaron Peshlakai A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science Approved November 2012 by the Graduate Supervisory Committee: Patrick Phelan, Chair Liping Wang Steven Trimble ARIZONA STATE UNIVERSITY December 2012 ABSTRACT Tesla turbo-machinery offers a robust, easily manufactured, extremely versatile prime mover with inherent capabilities making it perhaps the best, if not the only, solution for certain niche applications. The goal of this thesis is not to optimize the performance of the Tesla turbine, but to compare its performance with various working fluids. Theoretical and experimental analyses of a turbine-generator assembly utilizing compressed air, saturated steam and water as the working fluids were performed and are presented in this work. A brief background and explanation of the technology is provided along with potential applications. A theoretical thermodynamic analysis is outlined, resulting in turbine and rotor efficiencies, power outputs and Reynolds numbers calculated for the turbine for various combinations of working fluids and inlet nozzles. The results indicate the turbine is capable of achieving a turbine efficiency of 31.17 ± 3.61% and an estimated rotor efficiency 95 ± 9.32%. These efficiencies are promising considering the numerous losses still present in the current design. Calculation of the Reynolds number provided some capability to determine the flow behavior and how that behavior impacts the performance and efficiency of the Tesla turbine. It was determined that turbulence in the flow is essential to achieving high power outputs and high efficiency. -

He emigrated in 1884 to the United States, where he became a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company eventually marketed. -

Technical White Paper
Technical White Paper North American Power Distribution Prepared By Brad Gaffney, P Eng. Newterra Ltd. 1291 California Avenue P.O. Box 1517 Brockville Ontario K6V 5Y6 www.newterra.com This document is intended for the identified parties and contains confidential and proprietary information.

Copyright 1992-2020 Newterra Ltd. Abstract The following is an overview of power generation, transmission, and distribution in North America. Electrical power is the lifeblood of our ever so gadget-filled, technological economy. For most, it’s just a flick of a switch or the push of a button; many end users don’t know or care about the complexities involved in the transportation of billions of kilowatts throughout the country. However, one man by the name of Nikola Tesla had a vision for the use of electrical power back in 1882 when he realized that alternating current was the key to efficient, reliable power distribution over long distances. One obstacle that had to be overcome was the invention of an alternating current AC motor. Tesla demonstrated his patented 1/5 horsepower two-phase motor at Colombia University on May 16, 1888. By 1895 in Niagara Falls, NY the world’s first commercial hydroelectric AC power plant was in full operation using Tesla’s motor. To this day almost every electric induction motor in use is based on Tesla’s original design. Introduction The purpose of this paper is to give the reader a basic understanding of the process involved in power generation, transmission/distribution, and common end-user configuration in North America. -

Tesla's Magnifying Transmitter Principles of Working
School of Electrical Engineering University of Belgrade Tesla's magnifying transmitter principles of working Dr Jovan Cvetić, full prof. School of Electrical Engineering Belgrade, Serbia [email protected] School of Electrical Engineering University of Belgrade Contens The development of the HF, HV generators with oscilatory (LC) circuits: I - Tesla transformer (two weakly coupled LC circuits, the energy of a single charge in the primary capacitor transforms in the energy stored in the capacitance of the secondary, used by Tesla before 1891). It generates the damped oscillations. Since the coils are treated as the lumped elements the condition that the length of the wire of the secondary coil = quarter the wave length has a small impact on the magnitude of the induced voltage on the secondary. Using this method the maximum secondary voltage reaches about 10 MV with the frequency smaller than 50 kHz. II – The transformer with an extra coil (Magnifying transformer, Colorado Springs, 1899/1900). The extra coil is treated as a wave guide. Therefore the condition that the length of the wire of the secondary coil = quarter the wave length (or a little less) is necessary for the correct functioning of the coil. The purpose of using the extra coil is the generation of continuous harmonic oscillations of the great magnitude (theoretically infinite if there are no losses). The energy of many single charges in the primary capacitor are synchronously transferred to the extra coil enlarging the magnitude of the oscillations of the stationary wave in the coil. The maximum voltage is limited only by the breakdown voltage of the insulation on the top of the extra coil and by its dimensions. -

AKA Clark Kent) Middle Name Is Joseph
Superman’s (AKA Clark Kent) Middle Name Is Joseph. What’s that?! There in the sky? Is it a bird? Is it a plane? No! It’s the Man of Tomorrow! Superman has gone by many names over the years, but one thing has remained the same. He has always stood for what’s best about humanity, all of our potential for terrible destructive acts, but also our choice to not act on the level of destruction we could wreak. Superman was first created in 1933 by Joe Shuster and Jerry Siegel, the writer and artist respectively. His first appearance was in Action Comics #1, and that was the beginning of a long and illustrious career for the Man of Steel. In his unmistakable blue suit with red cape, and the stylized red S on his chest, the figure of Superman has become one of the most recognizable in the world. The original Superman character was a bald telepathic villain that was focused on world domination. It was like a mix of Lex Luthor and Professor X. Superman’s powers include incredible strength, the ability to fly. X-ray vision, super speed, invulnerability to most attacks, super hearing, and super breath. He is nearly unstoppable. However, Superman does have one weakness, Kryptonite. When exposed to this radioactive element from his home planet, he becomes weak and helpless. Superman’s alter ego is mild-mannered reporter Clark Kent. He lives in the city of Metropolis and works for the newspaper the Daily Planet. Clark is in love with fellow reporter Lois Lane. -
War of the Currents
An Electric Battle A WebQuest for War of the Currents Introduction At the turn of the twentieth century, the War of the Currents had a clear winner—Tesla and his alternating current. However, direct current survived into the twenty-first century. As recently as 2007, some parts of Manhattan were finally converted to alternating current. The transition from direct current to alternating current begin in the late 1920s but took decades, in part, because the foundation of New York City’s energy grid was build by Edison’s company. Task Your task is to research the everyday devices credited to Edison and Tesla. You will compare these inventor’s influences by creating a script for a 5-min mock “debate” between Edison and Tesla in which they debate their influences on today’s and future technology. Process Use the resources listed in the Resources section to begin your research. The Web sites listed are good starting points, but further Internet research will be necessary. Record your answers to the following questions. 1. What was the relationship between Tesla and Edison prior to the War of the Currents? 2. Both Tesla and Edison were prolific inventors. If the two were competing to obtain the most number of patents filed, who wins and by what margin? 3. Did any of Tesla’s or Edison’s inventions build upon one another or work together to bring about new technology? 4. Could direct current make a comeback? Explain your answer. Write a Script Write a script for a 5-min mock debate between Edison and Tesla, in which each tries to convince the audience that he was the more influential inventor. -
Wireless Power Transmission
International Journal of Scientific & Engineering Research, Volume 5, Issue 10, October-2014 125 ISSN 2229-5518 Wireless Power Transmission Mystica Augustine Michael Duke Final year student, Mechanical Engineering, CEG, Anna university, Chennai, Tamilnadu, India [email protected] ABSTRACT- The technology for wireless power transfer (WPT) is a varied and a complex process. The demand for electricity is much higher than the amount being produced. Generally, the power generated is transmitted through wires. To reduce transmission and distribution losses, researchers have drifted towards wireless energy transmission. The present paper discusses about the history, evolution, types, research and advantages of wireless power transmission. There are separate methods proposed for shorter and longer distance power transmission; Inductive coupling, Resonant inductive coupling and air ionization for short distances; Microwave and Laser transmission for longer distances. The pioneer of the field, Tesla attempted to create a powerful, wireless electric transmitter more than a century ago which has now seen an exponential growth. This paper as a whole illuminates all the efficient methods proposed for transmitting power without wires. —————————— —————————— INTRODUCTION Wireless power transfer involves the transmission of power from a power source to an electrical load without connectors, across an air gap. The basis of a wireless power system involves essentially two coils – a transmitter and receiver coil. The transmitter coil is energized by alternating current to generate a magnetic field, which in turn induces a current in the receiver coil (Ref 1). The basics of wireless power transfer involves the inductive transmission of energy from a transmitter to a receiver via an oscillating magnetic field.
