Abstract

Aerodynamics of horizontal axis wind turbine blades of a simple experimental model with an active flow control using a DBD plasma actuator has been studied by large-eddy simulations based on a high-order accurate and resolution computational method. Large-scale parallel computations have been conducted using message passing interfaces and 9,584 cores of the K computer. Results correspond to first revolution after the DBD plasma actuator starts have been presented. The impacts of the DBD plasma actuator on flow fields around the blades have been discussed. Up to a 14% increase in revolution-averaged torque generation has been attained. Moreover, this improvement of torque generation due to the DBD plasma actuator has been similar to those reported in the experiment.
