Lab-scale measurements of wind farm blockage effects

The inflow an individual wind turbine experiences in a farm layout is strongly dependent on flow interaction effects with the turbines surrounding it. In addition to well-known wake flows, lateral and upstream effects, commonly described as blockage have also recently gained some attention. this work, measurements induction zone of neighboring are presented for different arrangements three seven porous actuator discs. It shown how zones discs merge into single when decreasing spacing between As result, central disc higher thrust force than its For two rows, aligned setup observed result larger velocity decrease offset arrangements.
