ESTIMATION OF MASS DISTRIBUTION IN ANNULAR COMBUSTOR OF GAS TURBINE IN COLD FLOW USING CFD TOOLS
Journal Title: International Journal of Electrical, Electronics and Mechanical Fundamentals (www.ijeemf.com) - Year 2012, Vol 3, Issue 1
Abstract
Since the gas turbine is an air-breathing engine, its performance is changed by anything that affects the density and/or mass flow of the air intake to the compressor. Ambient weather conditions are the most obvious changes from the reference conditions of 59 F/15 C and 14.7 psi /1.013 bar. Ambient temperature affects the output, heat rate, heat consumption, and exhaust flow of a single-shaft. Each turbine model has its own temperature effect curve, as it depends on the cycle parameters and component efficiencies as well as air mass flow. The air density reduces as the site elevation increases. While the resulting airflow and output decrease proportionately, the heat rate and other cycle parameters are not affected. The present paper concentrated on the mass distribution inside the annular combustor at different location and varying diameter size with the help of CFD tools for better estimation of performance of gas turbine.
