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. -

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. -

Disc Thickness and Spacing Distance Impacts on Flow Characteristics of Multichannel Tesla Turbines
energies Article Disc Thickness and Spacing Distance Impacts on Flow Characteristics of Multichannel Tesla Turbines Wenjiao Qi, Qinghua Deng * , Yu Jiang, Qi Yuan and Zhenping Feng Shaanxi Engineering Laboratory of Turbomachinery and Power Equipment, Institute of Turbomachinery, School of Energy and Power Engineering, Xi’an Jiaotong University, Xi’an 710049, China; [email protected] (W.Q.); [email protected] (Y.J.); [email protected] (Q.Y.); [email protected] (Z.F.) * Correspondence: [email protected] Received: 9 November 2018; Accepted: 20 December 2018; Published: 24 December 2018 Abstract: Tesla turbines are a kind of unconventional bladeless turbines, which utilize the viscosity of working fluid to rotate the rotor and realize energy conversion. They offer an attractive substitution for small and micro conventional bladed turbines due to two major advantages. In this study, the effects of two influential geometrical parameters, disc thickness and disc spacing distance, on the aerodynamic performance and flow characteristics for two kinds of multichannel Tesla turbines (one-to-one turbine and one-to-many turbine) were investigated and analyzed numerically. The results show that, with increasing disc thickness, the isentropic efficiency of the one-to-one turbine decreases a little and that of the one-to-many turbine reduces significantly. For example, for turbine cases with 0.5 mm disc spacing distance, the former drops less than 7% and the latter decreases by about 45% of their original values as disc thickness increases from 1 mm to 2 mm. With increasing disc spacing distance, the isentropic efficiency of both kinds of turbines increases first and then decreases, and an optimal value and a high efficiency range exist to make the isentropic efficiency reach its maximum and maintain at a high level, respectively. -
Wireless Power Transmission
IOSR Journal of Electrical and Electronics Engineering (IOSR-JEEE) e-ISSN: 2278-1676,p-ISSN: 2320-3331, Volume 9, Issue 3 Ver. II (May – Jun. 2014), PP 01-05 www.iosrjournals.org Wireless Power Transmission 1Sudha Bhutada(Senior Lect.), 2Punit Maheshwari(R&D Eng.) 1EE Dept.SV Polytechnic College Bhopal, India 2VLSI Dept. Navigator Technologies Bhopal, India Abstract: The concept of wireless power transmission method is as old as we are using electricity. N. Tesla the father of wireless power transmission was the first to give an idea of wireless power transmission and he was keenly interested in lightning the world without using wires (WPT).Since then series of experiments were made to make feasible transmission of power where it is not possible and commercially viable by advances, inventions in electronic devices in this field. In this paper we present the concept of wireless power transmission from one place in turn to another. This concept is mainly used for reducing the transmission and distribution losses. This in turn reduces the cost of transmission and distribution and also the cost of electrical energy for the consumers. In this paper we discussed the methods, recent developments in WPT, its merits, demerits and applications. Keywords: Wireless Power Transmission WPT, Radio Frequency RF I. Introduction We know our present system of overhead transmission and distribution has biggest disadvantage is percentage of power loss is around 26 to 28 % during transmission and distribution which is because of resistance of wires of grid. WRI (World resources Institute) says that India's electricity grid has highest T&D losses in the world around 27%. -

However, its real-world implementations were limited by the difficulty to maintain laminar flow between rotor disks, transient efficiencies during rotor acceleration, and the lack of other applications that fully utilize the continuous flow outputs. All of the aforementioned limits of Tesla turbines can be addressed by scaling to the microfluidic flow regime. Demonstrated here is a microscale Tesla pump designed and fabricated using a Digital Light Processing (DLP) based 3D printer with 43 µm lateral and 30 µm thickness resolutions. The miniaturized pump is characterized by low Reynolds number of 1000 and a flow rate of up to 12.6 mL/min at 1200 rpm, unloaded. It is capable of driving a mixer network to generate microfluidic gradient. The continuous, laminar flow from Tesla turbines is well-suited to the needs of flow-sensitive microfluidics, where the integrated pump will enable numerous compact lab-on-a-chip applications.

Prodigal Genius BIOGRAPHY of NIKOLA TESLA 1994 Brotherhood of Life, Inc., 110 Dartmouth, SE, Albuquerque, New Mexico 87106 USA
Prodigal Genius BIOGRAPHY OF NIKOLA TESLA 1994 Brotherhood of Life, Inc., 110 Dartmouth, SE, Albuquerque, New Mexico 87106 USA "SPECTACULAR" is a mild word for describing the strange experiment with life that comprises the story of Nikola Tesla, and "amazing" fails to do adequate justice to the results that burst from his experiences like an exploding rocket. It is the story of the dazzling scintillations of a superman who created a new world; it is a story that condemns woman as an anchor of the flesh which retards the development of man and limits his accomplishment--and, paradoxically, proves that even the most successful life, if it does not include a woman, is a dismal failure. Even the gods of old, in the wildest imaginings of their worshipers, never undertook such gigantic tasks of world- wide dimension as those which Tesla attempted and accomplished. On the basis of his hopes, his dreams, and his achievements he rated the status of the Olympian gods, and the Greeks would have so enshrined him. Little is the wonder that so-called practical men, with their noses stuck in profit-and-loss statements, did not understand him and thought him strange. The light of human progress is not a dim glow that gradually becomes more luminous with time. The panorama of human evolution is illumined by sudden bursts of dazzling brilliance in intellectual accomplishments that throw their beams far ahead to give us a glimpse of the distant future, that we may more correctly guide our wavering steps today. Tesla, by virtue of the amazing discoveries and inventions which he showered on the world, becomes one of the most resplendent flashes that has ever brightened the scroll of human advancement. -
