The Lift and Drag on a Flat Plate at Low Reynolds Number via Variational Methods* By
The problem of determining the low Reynolds number lift and drag on a flat plate in Oseen flow is treated by the application of a variational principle due to Levine and Schwinger. This approach circumvents the difficulty which has limited previous results to drastically low values of the Reynolds number. In particular, an asymptotic form for the drag coefficient is derived, and found to be sui...
متن کاملPrandtl - Batchelor flow past a flat plate with a forward - facing flap
Two-dimensional steady inviscid flow past an inclined flat plate with a forward-facing flap attached to the rear edge is considered for the case when a vortex sheet separates from the leading edge of the flat plate and reattaches at the leading edge of the flap, with uniform vorticity distributed between the vortex sheet and the body. Solutions are found for a particular geometry and a range of...
متن کاملHybrid RANS/LES of plane jets impinging on a flat plate at small nozzle-plate distances
A k-ω based hybrid RANS/LES (Reynolds-averaged Navier–Stokes/large eddy simulation) model is tested for simulation of plane impinging jets at various nozzle-plate distances (H/B), where H is the distance and B is the slot’s width) and various Reynolds numbers (based on the slot’s width and the velocity in the symmetry plane). The studied combinations are H/B = 2 for Re = 10 000, H/B = 4 for Re ...
متن کاملObservations of Cavitation on a Three-dimensional Oscillating Hydrofoil
A test apparatus was designed and constructed to observe the effect of sinusoidal pitching oscillations on the cavitation of thredimensional hydrofoils. The apparatus is capable of oscillating hydrofoils at a rate up to 50 Hz and provides for adjustments in oscillation amplitude and mean angle of attack. Observations of the effect of pitching oscillation on cavitation have been made for a NACA ...
متن کاملClosed-Loop Control of Vortex Shedding on a Two-Dimensional Flat-Plate Airfoil at a Low Reynolds Number
Openand closed-loop control of vortex shedding in two-dimensional flow over a flat plate at high angles of attack is numerically investigated at a Reynolds number of 300. Unsteady actuation is modeled as a body force near the leading or trailing edge, and is directed either upstream or downstream. For moderate angles of attack, sinusoidal forcing at the natural shedding frequency results in pha...
