Research Data of Microturbine Nozzles with Outlet Angles Under 9 Degree

The article presents the experimental data of microturbine stages with small outlet angles of nozzle. The main aim of the research was to identify the complicated variation of studied microturbines effectiveness with different examined factors. The research of the model stages of microturbines with small outlet angles of nozzle was carried out with the analysis of the results based on statistical methods revealed relatively high efficiency for this class turbines. So, the continuation of the research in this field seems to be promising. Maximum efficiency of model stages was 0.62 with optimal combination of arrangement factors and operation conditions which were defined by imitation research with mathematical model of regression type.
