High-order accurate simulations of unsteady flow past plunging and pitching airfoils
Spectral difference method Plunging Pitching
2015/7/3
This paper presents simulations of unsteady flow past plunging and pitching airfoils using a high-order spectral difference (SD) method. Both third-order and fourth-order SD methods are employed...
Effect of Pitching Delta Wing on Vortex Structures with and without Impingement Plate
PIV Delta wing Vortex breakdown Angle of attack Pitching
2009/10/12
Flow past the leading edge of a delta wing oscillating about its mid-cord in a pitch plane with a reduced frequency of K=0.74 generates primary vortices having mostly elongated shapes. Their shapes an...
Characteristics of Longitudinal Motions of a Planing Craft in Head Waves at Very High-Speed—Effect of Surging on Heaving and Pitching—
High-Speed Planing Craft Stability Longitudinal Motion Surge Heave Pitch
2009/5/12
In this study, characteristics of longitudinal motions of a planing craft running at very high-speed in regular head waves are experimentally and theoretically investigated. The results of experiments...
