ASSESSMENT 3: INDIVIDUAL PROJECT PROPOSALFORMAT AND PERCENTAGE RUBRICExecutive Summary:The purpose of this paper is to put emphasis on the Tesla turbine, which and beendiscovered and patented by Nikola Tesla in the year 1913. This can be described asthe bladeless centripetal flow turbine with higher efficiency than gas turbine or anyother engine or machine. It is being referred as the bladeless turbine because in thismachine, fluid is being used in the place of the blades in manner to provide motionto the discs installed within the device. Boundary layer effect is being used withinthe system in the place of the fluid that is impinging over the blades to make theblades moving. It is also being called as the boundary layer turbine, prandtl layerturbine, and cohesion type turbine. It is being referred by many researchers as themultiple disk centrifugal pumps. This paper produces the whole working of theengine or the machine presented. In this report items those have been used as theinput are referred as the fuel as in engineering language every supply that is beingused to generate energy or transferred from one energy ton other is represented asthe fuel. This report presents how different moving parts of the machine can affectthe overall efficiency of the machine and how it can be used in beneficial manner.Certain gaps were identified in the execution of the project that includes theconfiguration of the disks relating to its diameter, spacing, and number in the rotorpart. There are various sub parts in the device that could result in the deficiency ofthe turbine. The project is a description of how we could achieve maximumefficiency through eliminating blades in a turbine engine and using fluid and itsproperties for the exchange of energy. Topic“Tesla turbine as the replacement for current turbine models”ObjectiveThe main purpose objective of this project proposal is to present a new turbine which is much efficient that any other turbine engines in the real world. This is an attempt to present a model of the turbine which could be applicable for 100%
efficiency in the system.Questions1.This project proposal will be evaluating following questions?2.Is there any turbine that could be used without blades?3.Is the turbine could be applicable for achieving approximately 100% efficiency?AimThe aim behind this project proposal is to introduce a bladeless turbine engine that would be capable of reaching efficiency up to 100% (or more than 95%).Sub goalsEliminate the factor of blade that could result in deficiency for the whole arrangement and replace it with fluid mechanism for providing motion to the disks.HypothesisTesla’s principle could be used for the development of an efficient turbine engine in manner to enhance the productivity and performance of the organization. Introduction:An engine can be represented as a machine that consumes fuels and convert it intomechanical energy. Despite of types of natural resources such as coal, air, water,petroleum, or any other source that could be used to produce energy can berepresented as fuel (Manfrida, Pacini & Talluri 2017). At the beginning of thetechnology era, two types engines were introduced for the social use namely,bladed turbines and piston engines. Bladed turbines were driven by steam that hasbeen generated through heating water or through moving water speed whereas;piston engines were driven by the combustion of gasoline and using the pressure ofthe gas exhausting (Yost 2015). Both the engines were complicated and timeconsuming in designing and developing for the application.
A machine is composed of various moving parts and similarly turbine is composedof piston, valves, bearings, rings, cams, and gaskets. Combining so manycomponents will alternatively affect the efficiency of the whole machine. Thisincreases the possibilities of less efficiency in the project however, emphasizing onthe efficiency of each components particularly could also result in the overallefficiency of the device. Tesla new engine is composed of bladeless turbines thatcould use fuel as the energy for being driven and will convert the fluid energy intomechanical energy with much higher efficiency. Literature Review:Gupta and Khodali (2013) presented their concern on the related topic andpresented a paper on the designing and operations of the turbo machines that isbased on the same principle of using fluid for the mechanism of energy conversion.It is being reported in the paper that turbo-machines are the devices those arehelpful in transferring the energy between the fluid and the rotor including thecompressors and the stators (Alrabie et al. 2017). The function of the energytransfer includes the transfer of energy to the rotor from the fluid and followed bythis, the compressor transfers the energy to the fluid from the rotor. There arevarious other designs of turbo-machines that could be applicable for the efficientuse of the machines and among them Tesla turbine is the one with highestefficiency rate (Song & Gu 2017). The Tesla turbine uses viscous and adhesionforce of the fluid (property of the fluid that sates force of attraction between themolecules) in manner to transfer energy. This machine is all about the boundarylayer effect that has been discussed in the below report that allows the disks to getenergy transferred by the fluid. Traum, Hadi and Akbar (2017) stated that there isvery wide range of the application of Tesla turbines that includes any type ofmixing of gas, liquid and solid without making damage to the machine. Anotherapplication is that it could be designed in manner to pump both the high viscousand low viscous fluid with less effort and much efficiency (Zahid et al. 2016).There have various practices practiced using this principle that includes pumpingthe fluids like live fish, fly ash, ethylene glycol, blood, rocks, and many othersubstances. Pandey et al. (2014) stated that various researchers have presentedvarious researches after the patent presented by Tesla in 1913 that werecontinuously attempting to effectively apply and improve the configuration of theTesla turbines in manner to get much efficient machine. There are certain factors
that might affect the proper functioning and efficiency of the Tesla machinesincluding number of the disks used in the rotor, their width, gap between twoconsecutive disks, jet angle at the inlet including its pressure and many more(Schosser et al. 2015). Holland (2016) stated that Tesla turbines basicallyfunctions on two basic principles of the fluids that include Viscosity, Adhesion thatare responsible for the mechanism of the conventional energy transfer in traditionturbines (Sharma 2016). Using these principles could be helpful in eliminating theblades that will alternatively presents an efficient output for the machine (Suha &Sengupta 2013). Various name has been provided to this machine because of itsmulti application and principle those have been stated in the below paragraph. Themost crucial objective for the Tesla turbines can be referred to the unavailability offriction within the conventional senses (Nelkel and Godinho 2015). The turbo-machinery based on Tesla principles are not capable of proving competitive in anapplication that could be applicable in wide range of different machines haveadequate performance and efficiency of the machines. Despite of all theadvantages there are certain disadvantages of the application of Tesla turbine andcould be stated as: the machine provides a low rotor torque (Hasan & Banzamia2014). Another disadvantage is that it can be stated as not suitable for the directexchange for the traditional pumps and turbines without changing theinfrastructure suited for the machine it is interacting with (Suha & Sengupta 2017).The machine has remained undeveloped from since 1913 when Tesla hadintroduced the facts, but the designs are still being improvised by variousresearchers till this date (Sivaramakrishnan 2017). The proofs related to theefficiency in comparison with the conventional turbines also needs certain moreresearches it is still questionable for the regular practice in the real life. Research Goals:The aim of this experiment is to establish relation between the efficiency of theturbine considering various objectives. These objectives include distance betweenthe turbine disks including the diameter and number of the disks of the turbine.Efficiency of the turbine is related to the efficiency of each objective including therotational speed, inlet temperature, pressure, angle, and velocity. For achieving themain objective of the project it is necessary to enhance the efficiency of the statorand rotor part.
