Direct numerical simulations of streamwise-localized turbulent flow (turbulent puff) in a horizontal square duct heated from above are performed at Richardson numbers 0 ? Ri ? 0.58 to characterize differences between isothermal and non-isotherma[...]![]()

Jiménez, J. ; Uhlmann, Markus ; Pinelli, Alfredo ; Kawahara, Genta | Cambridge University Press | 2001The behaviour of turbulent shear flow over a mass-neutral permeable wall is studied numerically. The transpiration is assumed to be proportional to the local pressure fluctuations. It is first shown that the friction coefficient increases by up [...]
