FLOW DISTRIBUTION OF FUEL NOZZLES FOR A COMBUSTOR IN A MICRO GAS TURBINE
摘要
Flow distribution of fuel nozzles for a combustor in a micro turbine is numerically investigated. The fuel
supply system for the present study has 12 single nozzles with a diameter of several hundred micrometers. A
uniform temperature distribution of a combustor should be achieved for maximizing the lives of the
turbine blades and nozzle guide vanes. For this, it is very important to uniformly supply fuel to a combustor. In
order to investigate flow distributions of fuel nozzles, numerical models for fuel nozzles are made and solved by
a commercial code, ANSYS FLUENT. An effect of a fuel nozzle diameter and fuel flow rates on flow
distribution of fuel nozzles is numerically investigated. As a result, non-uniformity is increasing as a diameter of
a single fuel nozzle increases. Finally, an appropriate diameter of a single fuel nozzle is suggested.
