Turbulence suppression by cardiac-cycle-inspired driving of pipe flow.
Scarselli, Davide; López-Alonso, José Manuel
; Varshney, Atul; Hof, Bjoern (Nature Publishing Group UK, 2023-09-06)
Flows through pipes and channels are, in practice, almost always turbulent, and the multiscale eddying motion is responsible for a major part of the encountered friction losses and pumping costs1. Conversely, for pulsatile ... -
Arrow-shaped elasto-inertial rotating waves.

Effects of inertia on the time-averaged propulsive performance of a pitching and heaving foil
Fernández-Feria, Ramón (Elsevier, 2023)
The inertia may play an important role in the unsteady behavior of a flapping foil. Of particular relevance in forward flapping locomotion is how the foil inertia may affect its time-averaged propulsive performance. This ... -

Nowadays, in the residential sector, a widely used heating, ventilation and air conditioning system is the ducted direct expansion inverter system based on the on/off control of a single zone, which cannot guarantee the ... -
Force and torque reactions on a pitching flexible aerofoil
Sanmiguel-Rojas, Enrique; Perona, J.L.; Fernández-Feria, Ramón (Cambridge, 2023)
Experimental measurements in a wind tunnel of the unsteady force and moment that a fluid exerts on flexible flapping aerofoils are not trivial because the forces and moments caused by the aerofoil's inertia and others ... -
