Time-varying wind-turbine wakes at high Reynolds numbers
Nathaniel J. Wei, Adina Y. Fleisher, John W. Kurelek +1
Wind turbines operating in the atmospheric boundary layer are constantly exposed to time-varying flow conditions. These disturbances often occur on similar time scales to wind-turb…
An analytical model for rotors in confined flow across operating regimes
I. M. L. Upfal, K. J. McClure, K. S. Heck +4
Rotors operating in confined flows, or blockage, are commonly encountered in wind and water tunnels, as well as in shallow or dense deployments of hydrokinetic turbines. Confinemen…
Spanwise wall forcing can reduce turbulent heat transfer more than drag
Amirreza Rouhi, Marcus Hultmark, Alexander J. Smits
Direct numerical simulations are performed of turbulent forced convection in a half channel flow with wall oscillating either as a spanwise plane oscillation or to generate a strea…
Understanding the effects of rotation on the wake of a wind turbine at high Reynolds number
Alexander Pique, Mark A. Miller, Marcus Hultmark
The wake of a horizontal-axis wind turbine was studied at with the aim of revealing the effects of the tip speed ratio, , on the wake. Tip speed ratios of $4…
