Overview

Demonstrates improved aerodynamic performance in vertical axis wind turbines using adaptive flaps and a trailing-edge splitter plate, suggesting significant efficiency gains.

Key Points

  • The aim is to explore flow control strategies to enhance the aerodynamic performance of vertical axis wind turbines (VAWT) using adaptive flaps and a splitter plate.
  • Conducted computational fluid dynamics (CFD) simulations.
  • Assessed the impact of adaptive flaps and trailing-edge splitter on a NACA 0015 airfoil.
  • Evaluated aerodynamic performance metrics across various angles of attack.
  • The adaptive flap positioned at the trailing edge showed optimal performance across different angles of attack.
  • The splitter plate improved the lift-drag ratio by approximately 61.6% in pre-stall conditions.
  • Flaps enhanced the power coefficient of the VAWT by up to 42.5% at specific wind speeds.
  • The splitter plate increased the power coefficient by about 29.4% at low tip speed ratios.
