Flow distribution of fuel nozzles for a combustor in a micro gas turbine is numerically investigated. The fuelsupply system for the present study has 12 single nozzles with a diameter of several hundred micrometers. A uniform temperature distribution of a combustor outlet should be achieved for maximizing the lives of theturbine 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 solvedby a commercial code, ANSYS FLUENT. An effect of a fuel nozzle diameter and fuel flow rates on flowdistribution of fuel nozzles is numerically investigated. As a result, non-uniformity is increasing as a diameterof a single fuel nozzle increases. Finally, an appropriate diameter of a single fuel nozzle is suggested.
