CFD and Structural Analysis of an Optically Accessible Combustor Sector Rig
Abstract:
Gas turbine technology has continuously evolved to develop small, powerful and efficient engines. The development of a combustor requires extensive experimental testing to obviate the various challenges encountered such as dynamics, high altitude relight, emissions and efficiency. A significant amount of an effort can be reduced by using combustors with optical access that can sustain high pressures and temperatures and performing comprehensive non intrusive multi parameter measurements for shortening the combustor development time. Design, development and fabrication of such a combustor is a formidable challenge and has been accomplished by only a few groups around the world. The objective of this project is to analyze the design of an optical combustor rig for high pressure and temperature experiments with optical access using a well known geometry the BOSS optical sector. For improving tools and methods for high temperature and pressure optical combustor design using CFD analysis. The test rig is modeled considering the high pressure chamber using a generic bluff body stabilized flame to simulate the likely temperature and flow conditions that would actually occur in such optical combustors. 3D CFD reacting flow analysis is done for various conditions to capture the flame size and shape and its effect the liner wall temperatures. It is seen that for most of the cases the liner where the quartz window is to be inserted remains at reasonably acceptable temperatures and is not affected by the flame.
