A high accuracy CFD (Computational Fluid Dynamics) scheme and a fine grid system are employed to capture the vortex. By locating the initial vortex well upstream of the airfoil, a parallel vortex interaction is simulated. The results are compared with the existing experimental data with good agreement. The initial miss distance, airfoil incidence, vortex rotation directions are chosen as the parameters for this parametric study. The BVI strength shows a high dependency on the initial miss distance and the feature changes with the airfoil incidence. The maximum BVI level occurs at the initial miss distance lower than the leading edge of the airfoil when the airfoil has incidences. The cause of the maximum BVI location change is observed due to the upwash exists ahead of the incident airfoil, which moves the vortex upward while the vortex is convected by the flow. At the maximum BVI level, the final miss distance between the vortex and the airfoil is nearly zero, the head-on BVI as so-called.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
