Preliminary Study of the Effects of Leading-Edge Serration on a Two-Section Planar Wing in ground-effect at Low Reynolds Number
Arnold Lafond-Saunierr, Simone Basile, Paloma Pizarro +4
A preliminary study has been conducted on the effects of serration on the leading-edge of a two-element trapezoidal wing placed both out-of- and in-ground effect. Aerodynamic perfo…
Reynolds number required to accurately discriminate between proposed trends of skin friction and normal stress in wall turbulence
Hassan Nagib, Peter Monkewitz, K. R. Sreenivasan
In Nagib, Chauhan and Monkewitz~\cite{NCM07} we concluded that nearly all available relations for zero-pressure-gradient boundary layers are in remarkable agreement over the…
Sensitivity study of resolution and convergence requirements for extended overlap region in wall-bounded turbulence
Sergio Hoyas, Ricardo Vinuesa, Peter Schmid +1
Direct Numerical Simulations (DNSs) are one of the most powerful tools for studying turbulent flows. Even if achievable Reynolds numbers are lower than those obtained with experime…
Utilizing indicator functions with computational data to confirm nature of overlap in normal turbulent stresses: logarithmic or quarter-power
Hassan Nagib, Ricardo Vinuesa, Sergio Hoyas
Indicator functions of the streamwise normal-stress profiles (NSP), based on careful differentiation of some of the best direct numerical simulations (DNS) data from channel and pi…
