Universal mean velocity profile in polymeric flows at maximum drag reduction
Francesco Serafini, Francesco Battista, Paolo Gualtieri +1
Provided a sufficient concentration of long-chain polymers in a Newtonian solvent, turbulent wall-bounded flows exhibit a universal state known as Maximum Drag Reduction (MDR). Thr…

Assessment of the point-wise approach for the Turbulent Settling of finite-size particles
Francesco Battistaa, Sergio Chibbarob, Paolo Gualtieria
We study the settling of suspensions of relatively large particles with a diameter of the order of ten Kolmogorov scales and density slightly larger than the carrier fluid in stati…

Bubbles enable volumetric negative compressibility in metastable elastocapillary systems
Davide Caprini, Francesco Battista, Pawel Zajdel +11
Although coveted in applications, few materials expand when subject to compression or contract under decompression, i.e., exhibit the negative compressibility phenomenon. A key ste…
