This work concentrates on the performance analysis of the twin spool mixed flow turbofan engine. The main target was to check out the effects of using hydrogen, gasoline and gas fuel within the performance qualities such as net thrust, certain fuel consumption and propulsive efficiency from the turbofan. Another aim of this kind of work was going to introduce the concept of exergy and thermoeconomics examination for twin spool combined flow turbofan engine and possess the components that contributes the most to the ineffectiveness of the engine. A universal simulation was carried out applying Gas Turb 11 application to obtain fair analysis effects that were tested with a current JT8D-15A turbofan engine. The parametric research was carried out for frequent value of mass stream rate of fuel and constant generator inlet temperatures for all three fuels. The end result were correctly obtained for people analysis instances and talked about accordingly.
Mechanised Engineering Academic Session: 2010/2011 Name of Student: Johnson Essien Ibok Supervisor: Doctor Lionel Ganippa Title: The Performance Characteristics and Thermodynamics Exergy and Thermoeconomics evaluation of a Double Spool Mixed Flow Turbofan Engine Operating at 30, 000ft at M0 zero. 8 applying Kerosene, natural Gas and Hydrogen Fuel. Subjective: This work focuses on the performance evaluation of a cal king spool blended flow turbofan engine. A generic simulation was performed using Gas Turb 10 software to obtain reasonable analysis results that had been verified having a real-time JT8D-15A turbofan engine. The parametric analysis was done to get constant value of mass flow rate of gasoline and continuous turbine outlet temperature for all three energy sources. The result were rightfully attained for these analysis cases and discussed accordingly. Objectives: The primary aim of this work is always to conduct the parametric routine simulation of a twin spool mixed stream turbofan engine and look into the overall performance characteristics of computer. Another purpose of this work is to show the effects of using hydrogen, Gasoline and natural gas fuel for the overall performance from the twin stove mixed flow turbofan engine. Also, the goal of this work is to expose the use of the second law of thermodynamics research known as exergy and thermoeconomics in examination the double spool merged flow turbofan engine Background/Applications: This function is applicable in so many methods when it comes to the complete performance marketing and feasibility analysis of any jet engine. This function relates to the aerospace and aviation industrial sectors since the turbofan engine is definitely amongst the vast number of plane engine utilized in propulsion of aircrafts. There is certainly increasing pressure in the aviation industry to minimize pollution and depletion of energy resources and maintaining fair investment expense and substantial overall performance. Therefore, this analysis was executed in hopes of coming up with a new solution to this problem. Results: The main bottom line drawn from the performance research is that hydrogen fuel produced the highest thrust level and the lowest specific fuel usage between the 3 fuels for the constant mass flow level of energy. Kerosene energy generated drive level can be increased whether it is mixed with a modest amount of hydrogen. The Exit plane velocity proportion remained constant despite the increasing bypass ratio for all three fuels at constant mass flow level of fuel. Using the exergetic analysis showed that the combustion chamber as well as the mixer added the most for the inefficiency of...
