Gui Program Development For Design Of Micro Gas Turbine Combustors

Designing a gas turbine combustor is a complex, iterative process, taking into account various restrictions related to the overall sizing and performance, including emissions and pressure losses. This paper describes a combustor design program that integrates the preliminary design processes in an organized manner to improve the design efficiency of a gas turbine combustor. The program was implemented in MATLAB software, realizing a user-friendly graphical user interface (GUI) to estimate the dimensions of the main components such as the annular casing and liner, and the swirl-stabilized burners. In addition, 2-D modeling in the program is capable of automatically visualizing the configuration of a designed combustor. With regard to the design of a swirler, which considerably affects the performance characteristics of the burner, such as overall pressure loss, various types of swirlers are incorporated into the program. The unknown swirler coefficient, which was determined by measuring the pressure loss, was observed to be similar to the swirler coefficient of conventional types.
