Design and Numerical Analysis of a Micro Gas Turbine Combustion Chamber

摘要: The interest in micro gas turbines has been steadily increasing. As a result, attention focused on obtaining optimal configurations for depending the applications which they are used. This paper presents CFD modeling results regarding an annular type combustion chamber, part of 800N turbine, predestined to equip small scale multifunctional airplane. Two have taken into consideration and 3D RANS numerical simulations conducted with use commercial software ANSYS CFX. liquid fuel droplets were modeled by particle transport model, tracks particles Lagrangian way. An initial droplet diameter 500µm imposed. obtained encouraging. flame was developed central area fire tube, its walls thus not being subjected high temperatures. Also, maximum temperatures primary zone tube. temperature then decreased tube's secondary dilution zone. will be validated conducting tests testing rig inside institute's Combustion Chamber Laboratory.
