The aerodynamics of a stationary wing in turbulent wake are investigated. Force and velocity measurements used to describe the unsteady flow. Various wakes studied with different dominant frequencies length scales. In contrast pre-stall angles attack, time-averaged lift increases substantially at post-stall attack as interacts von Kármán vortex street experiences temporal variations effective a...

Aerodynamics of trucks and other high sided vehicles is of significant interest in reducing road side accidents due to wind loading and in improving fuel economy. Recognizing the limitations of conventional wind tunnel testing, considerable efforts have been invested in the last decade to study vehicle aerodynamics computationally. In this paper, a three-dimensional near field flow analysis has...

Parachute aerodynamics involves an interaction between the flexible, elastic, porous parachute canopy and the high speed airflow (relative to the parachute) through which the parachute falls. Computer simulation of parachute dynamics typically simplify the problem in various ways, e.g. by considering the parachute as a rigid bluff body. Here, we avoid such simplification by using the immersed b...
