    Descripció del contingut i pla d'activitats:
    In the design and analysis of gas turbines, these are modeled from individual components that are pieced together. The objective of the project is to define types of modules through the input and output parameters that govern interaction with other types of modules. The different modules should contemplate all possibilities in terms of interrelation with other modules, so that their internal operation can be seen as a black box and, therefore, independently improved as finer modeling becomes possible. Each type of module will initially be implemented in its simpler form so that engine operation can be tested from early on in the project. Finer modeling will then be incorporated to modules in an orderly way.

    This project will concentrate on identifying the input/output parameters needed to model turbomachinery (fan, compressor and turbine) as well as defining a number of other secondary modules to represent additional components. A simple computational model of each of the aforementioned parts will be produced at the final stage.

    Coordination with at least two other projects focusing on other components is essential, as the various modules will have to be assembled into common applications for simulation. Compatibility among is therefore mandatory.

     
    Overview (resum en anglès):
    This project focuses in the creation of a program which will be a tool for helping in the design and simulation for gas turbine applications, allowing to the user to perform later the results to his designs. That’s why this tool must be versatile and allows working with a single module or a group of them in function of the user necessities. Also the fact of modularize allows to delimitate and perform effectively as well the modeling and the programing of the components. In this project this studied modules will be related with turbomachinery inside a gas turbine.
    For modeling successfully these components it will be necessary some theoretical bases for introduce us to the subject to simulate like thermodynamics, mechanics, numerical or programming bases. In this way, the desire is to not only focus on these more relevant aspects of the simulation being carried out, but give a broader view and leave, in a theoretical way, future possibilities to implement more complex modules and extensions. So, will be started whit a simple thermodynamic process in the first version and arrive to direct numerical simulations (DNS) in latest versions, incorporating efficiencies caused because of the losses or implementation of empiric data.
    In this project will be done a study of the obtaining results in the program, and then those results will be compared with other references that contain similar final values. So, this will allow us to know the progress and efficiency of program. Also, this kind of comparisons will be a way to detect possible errors that can appear. These errors could be in the program or can be theoretical, any way, we must to correct or justify them if it’s needed.
    Finally, it must be said, that this final year project is only a small part of a larger project that aims to fully simulate the behavior of a gas turbine engine in the most realistic way possible. So, in order to see the full scale of the project, it remains to be completed with heat transfer and subtracting modules and conduction, diffusion and expansion of the gases modules. These modules will be done in simultaneously in the projects named Gas Turbine Design & Analysis Tool: Ducting Components and Gas Turbine Design & Analysis Tool: Heat Transfer Components.
