英文摘要: Abstract(#br)The flow past a square cylinder attracts extensive interests in the past decades. It also has been used for the drag reduction research of flow past a bluff body. The present study performs Very-Large Eddy Simulation (VLES) of passive drag reduction for a square cylinder based on the open-source CFD (Computational Fluid Dynamics) toolbox, OpenFOAM. The newly developed VLES method is implemented in OpenFOAM and also assessed in the complex flow control simulations. For the drag reduction, a passive flow control method is used, i.e. cutting the corners at the front edge of the square cylinder. Firstly, a control method from previous studies (referred as to CM-1, i.e. control method 1) is adopted and numerical investigations are performed. Based on that, a new control method,...
