| چکیده | ||
| در میان انرژی‌های تجدیدپذیر، انرژی باد یکی از جذاب‌ترین روشهای تولید انرژی مکانیکی هست و روشهای متفاوت کنترل جریان اعم از فعال، شبه فعال و غیرفعال توسط محققان مختلفی بررسی شده‌است. برای کنترل جریان سیال به روش فعال روی پره‌ی توربین بادی، عملگر تخلیه کرونا بر اساس پلاسما مناسب‌ترین روش برای کاهش جدایش جریان سیال بر روی پره توربین بادی محسوب می‌شود. در این مقاله، یک شبیه‌سازی عددی برای ادغام کنترل بار فعال با استفاده از تخلیه‌ی کرونا بر اساس محرک پلاسما بر روی تیغه با زبری معین ارائه شده‌است. اثرات زبری، ولتاژ و فرکانس محرک بر پارامترهای آیرودینامیکی مانند نقطه جدایی جریان سیال، ضرایب لیفت و درگ نشان داده شده‌است. نتایج کارفعلی نشان داد که با افزایش ولتاژ و فرکانس محرک‌های پلاسما، ضریب لیفت افزایش می‌یابد. به طور کلی، در نظر گرفتن زبری برای سطح بیرونی پره، ضریب فشار بحرانی را تا حدود 50 درصد در مقایسه با سطح کاملاً صاف کاهش می‌دهد. | ||

| چکیده [English] | ||
| The use of renewable energy has recently become very common in most countries of today's society. Among these renewable energies, wind energy is one of the most attractive methods of mechanical energy production, and different methods of flow control, including active, semi-active and passive, have been investigated by various researchers. To control the fluid flow in an active way on the wind turbine blade, the corona discharge actuator based on plasma is considered the most appropriate method to reduce the fluid flow separation on the wind turbine blade. In this paper, we present a numerical simulation to integrate active load control using a corona discharge based on plasma actuators over the roughness blade. Effects of roughness, actuators voltage and frequency on aerodynamics parameters such as separation point, lift and drag coefficients have been showed. Present results showed that, the lift coefficient increase with increase in the voltage and frequency of plasma actuators. Overall, using the roughness for outer surface of blade would decrease the critical pressure coefficient by approximately 50% compared to that for the smooth surface. | ||
