A Separation Control CFD Validation Test Case. Part 1: Baseline & Steady Suction

A High-Order Compact Finite-Difference Scheme for Large-Eddy Simulation of Active Flow Control

“…For configuration D, losses were only lowered by 39%. [75,76] with and without flow control. In the control cases, both steady suction and zero net mass flux blowing/suction were considered.…”

Reynolds-Averaged Navier-Stokes Analysis of Zero Efflux Flow Control over a Hump Model

“…There was only limited comparison with oscillatory synthetic jet data because the unsteady experiment was not completed at the time of the workshop. The steady experimental results were documented in Greenblatt et al, 4 with wall shear stress measurements for the no-flow-control case documented in Naughton et al 5 After the CFDVAL2004 workshop, extensive time-accurate data became available for the oscillatory flow-control case. 6 Measurement uncertainties were also documented (±0.001 for surface pressure coefficients, less than 3% for velocities, and ±10% for turbulence quantities).…”

Boundary layer separation from continuous surfaces with increasingly complex topography: a comparative LES, hybrid LES/RANS and RANS study

“…The flow cases investigated are featured by a systematic increase in the wall complexity: a backward-facing step flow (Re H =5540; Exp., Kasagi and Matsunaga, 1995), flow in a plane diffuser (Re m =18000; Exp., Obi et al, 1993, Buice andEaton, 1997), periodic flow over an axisymmetric hill (Re H =10800; LES, Froehlich et al, 2005) and flow over a hump (Re C =936000; Exp., Greenblatt et al, 2004). The main objective of the present work is the in-depth analysis of the flow structure aiming at establishing appropriate criteria for the flow unsteadiness characterization, marking the RANS method capabilities with respect to capturing correctly the mean flow characteristics relative to the LES-related methods.…”
