Numerical studies of the wake of a plate normal to a free stream
Wake flows form an important class of problems in fluid mechanics both from fundamental and application points of view. While the geometry of a circular cylinder has received much attention, that of a flat plate has not. At present, numerical simulations have not been reported in significant …

Electro-magnetic control of cylinder wake
… closed-loop control algorithms for manipulating wake flows past a solid cylinder in an electrically low-conducting fluid (e.g. seawater). The intent is to avoid both vortex shedding and flow separation from the body. It is desired to reduce the mean drag significantly and prevent the lift from …

The Two Point Correlation Structure of a Cylinder Wake
… time correlation function was measured in the wake of an untripped circular cylinder at a Reynolds number of 60 000. This correlation serves as the complete inflow boundary condition for an open rotor ingesting inhomogeneous turbulence. An important aspect of the turbulence ingestion problem is …

Relating skewness and Fourier harmonics in low Reynolds number wake flow
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2026-05-01

Prediction of Trailing Edge Noise from Two-Point Velocity Correlations
… correlation from Reynolds stress data in wake flows, originally developed by Devenport et al. (1999, 2001) and Devenport and Glegg (2001), was adapted to boundary-layer type flows. This method, using Reynolds stresses and the prescription of a lengthscale to extrapolate the full two-point …

Study of Far Wake of a Surface-Mounted Obstacle Subjected to Turbulent Boundary Layer Flows
… obstacle to quantify its effects on the far wake. The obstacle chosen for this study was a 3:2 elliptical nose NACA 0020 tail wing-body (Rood body), approximately of height equal to the boundary layer thickness at one of the measurement locations of the flow. The experiments were performed by …

Reduced-order modeling of non-Boltzmann thermochemistry and radiation for hypersonic flows
… aerothermal environment during hypersonic flows is determined by the interaction between a multitude of disparate physical phenomena with varying characteristic time scales. The multi-physics nature of this flight regime renders the task of accurately estimating vehicular characteristics …
