  In this paper, we examined the low speed wind-tunnels. Our goal is to construct an open flow system windtunnel that can be utilized in our measurements. To make such a wind-tunnel we needed to build a prototype and calibrated with the help of measurements. Than we determined the flow at the area of measurement. Finally results of the measurements satisfied our expectations. Although there is still much more in development that we would like to do based on the newly gained experience.

  Our goal was to develop a wind turbine system which could be applied in urban areas where the wind power has low potential, such as the cities in the “Alföld” region. The proposed system is able to harness more wind power at lower wind velocity than the commonly used ones, by using advantageo us properties of the flow in tunnels.
