内容記述 | In this study, flow computations are performed around three-dimensional high-lift configurations on multi-block structured and hybrid unstructured meshes. The objective is to assess and improve the reliability in simulating the flow around such devices. Three-dimensional computations on three-element trapezoidal wings with fuselage are performed. Two configurations with full-span flap and part-span flap are used. Ways to improve the reliability of structured and unstructured meshes are discussed by comparing the results. It is shown that the prediction of aerodynamic forces is quite reasonable even on the unstructured mesh at both configurations. Mesh sensitivity to the flow separation in the corner flow near the junction of wing and fuselage, which largely affects the prediction of aerodynamic forces, is also investigated. Coarse mesh resolution at the corner on the structured mesh on which stretched mesh elements are generally used in the spanwise direction results in overestimation of the flow separation. Quantitative prediction of the flow separation in the corner flow near the junction is one of the important problems for more accurate prediction of aerodynamic forces. | |||||
