Asymptotic turbulent friction in 2D rough-walled flows
Alexandre Vilquin, Julie Jagielka, Simeon Djambov +6
The friction f is the property of wall-bounded flows that sets the pumping cost of a pipeline, the draining capacity of a river, and other variables of practical relevance. For hig…
Kolmogorovian turbulence in transitional pipe flows
Rory T. Cerbus, Chien-chia Liu, Gustavo Gioia +1
As everyone knows who has opened a kitchen faucet, pipe flow is laminar at low flow velocities and turbulent at high flow velocities. At intermediate velocities there is a transiti…
Janus spectra in two-dimensional flows
Chien-Chia Liu, Rory T. Cerbus, Pinaki Chakraborty
In theory, large-scale atmospheric flows, soap-film flows and other two-dimensional flows may host two distinct types of turbulent energy spectra---in one, , the spectral expone…
Macroscopic effects of the spectral structure in turbulent flows
Tuan Tran, Pinaki Chakraborty, Nicholas Guttenberg +5
Two aspects of turbulent flows have been the subject of extensive, split research efforts: macroscopic properties, such as the frictional drag experienced by a flow past a wall, an…
The turbulent mean-velocity profile: it is all in the spectrum
Gustavo Gioia, Nicholas Guttenberg, Nigel Goldenfeld +1
It has long been surmised that the mean-velocity profile (MVP) of a pipe flow is closely related to the spectrum of turbulent energy. Here we perform a spectral analysis to identif…
Marangoni shocks in unobstructed soap-film flows
T. Tran, P. Chakraborty, G. Gioia +2
It is widely thought that in steady, gravity-driven, unobstructed soap-film flows, the velocity increases monotonically downstream. Here we show experimentally that the velocity in…
