A bird or insect sized flapping wing Micro Aerial Vehicle (MAV) whose wingspan is of the order of a few centimeters cannot be physically built or flown today; they can be designed, tested, flown and studied on the computer using numerical simulation technique. While finalizing a design is quite significant in case of MAV, understanding the flow field environment in which MAVs fly is equally a requirement. The flow field environments encountered by Micro Air Vehicles are fundamentally unsteady - whether for fixed-wing, rotary-wing or flapping-wing configurations. High lift generation is...
