In this study, wind tunnel experiments were conducted to clarify the wake behavior of vertical axis wind turbines and the loads generated on wind turbines operating in the wake. To clarify the wake behavior, the downstream velocity field was measured for cases with one and two upstream wind turbines. To clarify the loads generated on the turbine operating in the wake, the rotational torque and streamwise force generated on the test turbine were measured in the downstream area of the turbine. As a result of the experiment, the wake of a vertical axis wind turbine has an asymmetric velocity distribution with respect to the rotor center, and that the load fluctuations occurring on a wind turbine operating at the boundary between the velocity deficit region and the freestream region are larger than those operating in the freestream region.
