Unsteady flow physics of airfoil dynamic stall
… were to perform a detailed analysis of the flow evolution, with particular emphasis on the underlying physical mechanisms, and to extract the dominant scales associated with the flow perturbations, for a canonical dynamic stall process. A series of unsteady surface pressure measurements, …

Numerical studies of unsteady flow past bluff bodies
Unsteady flow past prismatic two dimensional bodies have been numerically studied by solving the full Navier-Stokes equations at Reynolds numbers up to 1000 to study onset of vortex shedding and early stages of flow evolution. Loads have been calculated for the trapezoid section by solving Poisson …

Unsteady flow over a 6:1 prolate spheroid
The flow over a 6:1 prolate spheroid undergoing transient maneuvers is studied. The Dynamic Plunge-Pitch-Roll (DyPPiR) model mount provides the unique capability to simulate truly unsteady maneuvers in a wind tunnel. The DyPPiR is presented along with several transducer systems used to study …

Applicability of Hydraulic Performance Graph for Unsteady Flow Routing
… of the hydraulic performance graph (HPG ) for unsteady-flow routing is investigated herein. The HPG is a summary of backwater profiles in a channel reach in terms of discharge and water stages at its downstream and upstream ends. Traditionally, in hydraulic flow routing the Saint-Venant …

Vortex-induced vibration of slender structures in unsteady flow
… the slender riser to oscillate, creating an unsteady and nonuniform flow profile along the riser. The purpose of this research is to develop a VIV prediction model for slender structures under top-end periodic motions. The key approach to this problem requires identifying the dimensionless …

Modeling Phosphorus Transport in a River Under Unsteady Flow Conditions
… which may occur due to varying velocity under unsteady flow condition. To solve this problem, various numerical methods were tested and the implicit Lagrangian method was selected, which showed least numerical dispersion, given a computational grid size. The model is applied to a 55-km stretch …

An Experimental Study of Unsteady Flow Over Airfoils Near Stall
… six airfoils did not exhibit low-frequency unsteady behavior near stall and the resulting lift fluctuations were very small (less than 0.040). These airfoils exhibited trailing-edge separation which moved forward on the airfoil as the angle of attack was increased into stall. The separation …

Characterization of unsteady flow processes in a centrifugal compressor stage
… have been implemented to characterize the unsteady loading on the rotating impeller blades in a modem centrifugal compressor. These consist of unsteady Reynolds-averaged Navier Stokes simulations of three-dimensional and quasi-two dimensional approximate models. The interaction between the …
