A perturbative model for predicting the high-Reynolds-number behaviour of the streamwise travelling waves technique in turbulent drag reduction
Marco Belan, Maurizio Quadrio
The background of this work is the problem of reducing the aerodynamic turbulent friction drag, which is an important source of energy waste in innumerable technological fields. We…
Experimental assessment of drag reduction by traveling waves in a turbulent pipe flow
Franco Auteri, Arturo Baron, Marco Belan +2
We experimentally assess the capabilities of an active, open-loop technique for drag reduction in turbulent wall flows recently introduced by Quadrio et al. [J. Fluid Mech., v.627,…
Highly under-expanded jets in the presence of a transverse density gradient
Marco Belan, Sergio De Ponte, Daniela Tordella
An experimental research concerning highly underexpanded jets made of different gases from the surrounding ambient is here described. By selecting different species of gases, it wa…
Determination of density and concentration from fluorescent images of a gas flow
Marco Belan, Sergio De Ponte, Daniela Tordella
A fluorescent image analysis procedure to determine the distribution of species concentration and density in a gas flow is proposed. The fluorescent emission is due to the excitati…
