Development of a Background-Oriented Schlieren (BOS) System for Thermal Characterization of Flow Induced by Plasma Actuators

Cold climate regions have great potential for wind power generation. The available energy in these is about 10% higher than other due to speeds and increased air density. However, usually favorable icing conditions that lead ice accumulation on the turbine blades, which turn increases weight of blades disrupts local airflow, resulting a reduction performance. Considering this problem, plasma actuators been proposed as devices simultaneous flow control deicing. These transfer momentum improving aerodynamic performances while producing significant thermal effects can be used prevent formation. application deicing, it very important investigate induced by devices. electromagnetic interference generated operation devices, there lack experimental techniques analyze them. In current work, background-oriented Schlieren system was developed presented new technique characterization plasma-induced flow. For first time, temperatures are characterized with different dielectric materials thicknesses. results demonstrate that, discharge, temperature increase applied voltage may achieve five times room temperature, proves deicing applications. discussed respect blades.
