Abstract/Summary Micro-turbines have been lately recognized as promising alternatives for powering unmanned aerial vehicles (UAVs), hybrid transport and small scale electricity generation. Due to their traditional use in military and recreational applications, a good deal of empirical and general data is available but little technical and scientific information about their behaviour, and in particular about their combustion characteristics can be obtained. Injection is widely recognized as a major controller of the combustion process in thermal machines such as diesel engines and gas turbines. In this paper a computational study is undertaken to identify the influence of the injection characteristics on the thermodynamic variables inside a commercial micro-turbine. Large eddy simulation is used for describing the turbulence. Statistical design of experiments is used to evaluate the influence of each factor and their interactions as well as for reducing the amount of simulations. Results indicate that changes in droplet size and injection velocity can improve the conditions at the outlet of the combustor.
