Nettet14. sep. 2024 · Abstract. The wing-wake interaction of flapping wings while hovering has been investigated, with the focus on the difference in wing-wake interaction between 2D and 3D flapping wings. Numerical simulations are conducted at a Reynolds number of 100, and the flapping configurations are divided into the 2D, quasi-3D and 3D categories. Nettet1 1. INTRODUCTION During the powered landing of spacecraft on the Moon or Mars, rocket exhaust plumes interact with the surface, altering the physical state of the landing area and creating potential hazards to the spacecraft and nearby hardware. The effects of plume-surface interactions (PSI) differ depending
