Abstract: This study investigates the influence of an annular coflowing air stream on the puffing behavior of a buoyant plume by employing the BiGlobal Linear Stability Analysis. An increase in the coflow is found to mitigate the ...

Abstract: Pressure flow due to vertical contraction occurs under a bridge when the river water level rises above the bottom chord of the bridge. The flow accelerates inside the contraction and diverges downstream of it, resulting ...

Abstract: The unsteady wake characteristics of a butterfly-shaped wing undergoing flapping and feathering motions are studied. A 4-bar quick return mechanism is used to generate the flapping motion. To achieve considerable feathering ...
