【 摘 要 】

The article deals with numerical and experimental investigation of wind flow in roof area and optimal design of input parts, where is possible to use IRWES system (Integrated Roof Wind Energy System). Orientation of some high-rise objects is suitable for using wind power. In the first phase, the selected building was investigated using CFD simulation for creating space for three small wind turbines in the area of two technical floors. By using 3D print technology, model of the structure in scale 1:300 with rough facade was created. Experimental measurements were performed in Boundary Layer Wind Tunnel in Bratislava. Measurements were made for 3 reference wind speeds, which fulfilled flow similarity of prototype and model. We have compared the results of the numerical simulations and experimental measurements and obtained information on the average wind speeds at the VAWT site. Comparison of the mean wind velocity and external wind pressure coefficient obtained by CFD simulation and experimental measurements showed a good match. Considering the annual average wind speed at about 100m above sea level, we compared the wind acceleration at the turbine site.
