3D Wind Field Construction with High Performance Computing and VR Visualization

INTRODUCTION

Simulation of wind currents near campus.Wind energy, as one of the cleanest renewable energy, is becoming increasingly important. Both the installed wind power and the generated energy are increasing by 30% per year world-wide. Economical performance of a wind turbine is determined by the efficiency of the blade. If the airflow over wind turbine blades could be controlled fully, the generation efficiency and thus the energy production would increase by 9%.

Air flows over wind turbine blades are typically complex unsteady turbulent features due to the changes in the angle of attack and to unsteady flow separation at high angles of attack. To accurately capture the important turbulent atmospheric boundary layer features is the key issue to successfully design and optimize wind turbine blades. Visualization technique can be very helpful in achieving this goal.


OBJECTIVES

  • For wind energy assessment – construct 3-D wind fields, generate wind power density map at different altitude through CFD calculation, visualization and simulation techniques can help to identify the optimized location for siting wind turbine;
  • For turbulent flow around wind turbine blades – visualization and simulation can capture the turbulent flow features around wind turbines in detail for better understanding the involved unsteady turbulent features.
  • For contaminant dispersion – visualization and simulation technique can help to predict the contaminant dispersion traces, which is promising in emergency response and homeland security related issue.
