Tesla TurbineExecutive SummaryThis assignment totally related with study and improvement initiative for tesla turbine and theirblade. To acquire certain knowledge and investigate the material for alteration of turbine diskswe have gone through several articles which are listed in the reference section, to obtain thecertain parameter related with turbine was calculated manually with the help of formula given bydifferent researchers. Finally we are able to suggest some design aspect and material for turbinedisk followed by conclusion.2 | P a g e

Tesla TurbineIntroductionA turbine is set of parallel discs on a uniaxial shaft, in housed by casing and rotating at very highspeed device. The patent right of this simple but effective device goes to Nikola tesla, whoinvented and given its own name to this turbine in 1913. This device is being used in modernestates to generate electrical power. Most of the business entities use electricity in carrying outits core activities. It took him much time to successfully invent this machine as it involvedvarious tests globally to arrive at an effective project. Use of no blades in rotating of the enginewas one of the most unique things invented by Nikola. This is because people believed that amachine can only move through the aid of blades at the centre which was contrary to Tesla`sthought. Tesla turbine has undergone changes over years and this has been just to make sure itsefficiency is also improved (Gingery, 2014). The main feature of this machine is that it is purely made of disks that don’t use blades togenerate power. When the internal motion is high, effect of wear and tear is reduced henceincreasing its efficiency. Another key factor that increases efficiency is the manner in which itwas constructed. It is light in nature hence high efficiency. The basic function includes that, fluidpulls itself forcefully through viscosity and adhesion of the surface layer of the fluid. When thefluid declines and adds force to the disks, it curves into the middle exhaust and since the rotarypart of the machine has got no outlets, it is strongly built. For this machine to work more perfect,the speed of disk rotation at the centre must be high. High motion generates more power henceincrease in its efficiency. The intensity of temperature also contributes a great deal when lookingat its functioning capabilities[ CITATION Chu15 \l 1033 ].Description and property of componentsIn general the material used in making parts of tesla turbines comes under AISI 4140 steelmaterial; the chemical composition generally contained in this steel is chromium 1%,molybdenum 0.8 % that is why its material has high tensile property, the young’s modulus of thismaterial is about 220 GPa, density is found as 7852 kg/m3, Poisson ration is equal as 0.29,4 | P a g e
