Abstract
The article presents the results of the investigation of a rotor assembly of a wind turbine with a horizontal axis of rotation. The rotor is equipped with a diffuser which is an integral part of the power generating unit. The research was carried out by means of the ANSYS Fluent software. The geometry used for the tests is a development version of the construction shown in patent application PL 412553 and is characterised by an adjustable angle setting of the rotor blades. The geometric model was obtained by 3D scanning of the actual rotor using the ZScaner scanner ®700. The calculations were carried out for the selected blade angle of attack from 0° to 90° separately for the version with and without the diffuser. The results from the conducted tests were used to determine the characteristics of the power generated by the turbine as a function of rotor speed. The secondary objective of the tests was to analyse the effect of the diffuser on the power generated by the entire rotor assembly.

The authors of the work [6] used an aerodynamic tunnel to find the optimal shape of the diffuser, and in addition to assess the effect of the diffuser on the performance of a small wind turbine
The purpose of this work was to examine a small wind turbine equipped with an external diffuser in the form of a ring
Summary
Renewable energy sources, including wind energy, are gaining increasing popularity all over the world. The analysis of the efficiency of a modern wind turbine with a vertical axis of rotation is presented in [4]. It is possible to equip the turbine with a specially designed external diffuser. This solution was used by the authors of the work [5], in which a turbine equipped with a diffuser in the form of a tube was tested in simulation and experiment. The authors of the work [6] used an aerodynamic tunnel to find the optimal shape of the diffuser, and in addition to assess the effect of the diffuser on the performance of a small wind turbine
