Gas turbine

When studing liquid fuel combustion in gas turbine combustor, complicated principals including reactive flow, spraying, turbulent flow, multiphase flow, convective and radiative heat transfer and their interactions should be considered. In recent 40 years combustion chambers have continuously improved structurally. Present combustion chambers are generally devided to three main groups: Can type, Can Annular type, and Annular type chambers. Combustion chambers consist of components such as swirler, injector, diffuser, liner, cooling holes, dilution holes and etc. A gas turbine combustion chamber classically has three zones: primary zone, secondary zone, and dilution zone. In primary zone, which is located between injector and primary jets,…

Technology, Engineering and Mathematics) and that's where I came in across this topic "The Gas Turbine". What is a Gas Turbine? Where are they being used? Why don't we have Gas Turbine cars out there for sale? How does a gas turbine work? I guess from my…

Two factors are required for proper operation of a gas turbine. One is expressed by Newton’s third law. The other is the convergent-divergent process. Convergent means approaching nearer together, as the inner walls of a tube that is constricted. Divergent means moving away from each other, as the inner walls of a tube that flares outward. Bernoulli’s principle is used in this process. The venturi of the common automobile carburetor is a common example of Bernoulli’s principle and the…

A comprehensive performance analysis of an EAHE could supply great help for the design and application of EAHE in gas turbine. At first the soil temperature at different depth along the year was evaluated to determine the optimum depth for high performance and low economical cost. Then the effect of structural factors including the pipe length and inner diameter, in addition the effect of air velocity passing through the pipe on the performance were studied. The air temperature at the inlet of…

General Electric Company is the world’s global digital industrial company that introduces software-defined machines to create solutions in the industry1. They have been a Fortune 500 company for 21 years2. GE is listed on the NYSE (New York Stock Exchange) in the United States, and many others for non-U.S. exchanges3. Over the years they have broadened their technologies and services into eight different industrial operating segments and one financial services operating segment4. Industrial…

would see me soldering an electrical circuit or building a model plane and say, “You’re going to be an engineer!” So I studied mechanical engineering, got a job with a big aerospace company, and I liked it. Intellectually, it was a perfect fit for me: solving intricate problems all day. But something was missing. It all seemed a little abstract: did this gas turbine engine component I designed have any direct impact on the world? Did it actually help anyone? I assumed if I took on bigger…

The analysis of turbines is no easy feat to accomplish. With an ever expanding need to generate efficient energy, a way to increase efficiency is to find ways to improve turbine technology. The best way to analyze different turbine set ups is the usage of a turbine test rig. There are multitudes of types of these rigs with reasons for and against them. These rigs are incredibly expensive to build and keep up. But they provide vital information about turbine performance and enable the improvement…

GA is search technique that is used in computing to get true or appropriate solutions to optimization and search problems. Inheritance, Mutation, Selection and crossover methods may apply for designing algorithms. Genetic algorithm is implemented as computer stimulation where the population of abstract representations of applicant solutions to optimization problem evolves towards the better solutions.Fig1 (d) shows the genetic algorithm phases. Basically it works on the principle of survival of…

Computer and Network Systems to perform wind projects with purpose to improve the performance of “smart” wind turbines and wind farms (Purdue Engineering Impact Magazine). The primary aim of the smart wind turbine is to reduce to unharnessed energy that results from the wake…

carbon dioxide is leading to global warming however, there is something that can help reduce the amount of greenhouse gas being put into our environment. Instead of using fossil fuels to provide energy we can start using wind power. Wind power is considered renewable energy because it continues to exist there is no end to wind. However, there are some negatives in the use of wind power. Before we examine the positive and negative of wind power we need a better understanding of what wind power is…
