Abstract
Low Reynolds number aerodynamics is important for various applications including high altitude unmanned vehicles, wind turbines and propellers. Few researches were concerned on this area. Low Reynolds number (60000,100000,300000,460000) flows around Eppler387 airfoil of different angles of attack (0°~12°) were simulated using Computational Fluid Dynamics (CFD). Transition shear-stress transport (SST) model which combined with the SST model and the model was demonstrated. Simulation results show good agreement with the experimental data. The model is able to predict the position of low Reynolds laminar separation bubbles and display the complex phenomenon of the flows, which can form the basis for solving boundary layer separation problem and designing of airfoil.
