Drag increase and turbulence augmentation in two-way coupled particle-laden wall-bounded flows Open

F. Battista, P. Gualtieri, J.-P. Mollicone, Francesco Salvadore, Carlo Massimo Casciola · 2023

The exact regularized point particle method is used to characterize the turbulence modulation in two-way momentum-coupled direct numerical simulations of a turbulent pipe flow. The turbulence modification is parametrized by the particle St…

Superhydrophobic surfaces to reduce form drag in turbulent separated flows Open

J.-P. Mollicone, F. Battista, P. Gualtieri, Carlo Massimo Casciola · 2022

The drag force acting on a body moving in a fluid has two components, friction drag due to fluid viscosity and form drag due to flow separation behind the body. When present, form drag is usually the most significant between the two, and i…

Structure of turbulence in temporal planar jets Open

A. Cimarelli, A. Fregni, J.-P. Mollicone, Maarten van Reeuwijk, Elisabetta De Angelis · 2022

A detailed analysis of the structure of turbulence in a temporal planar turbulent jet is reported. Instantaneous snapshots of the flow and three-dimensional spatial correlation functions are considered. It is found that the flow is charact…

Transition from shear-dominated to Rayleigh–Taylor turbulence Open

Stefano Brizzolara, J.-P. Mollicone, Maarten van Reeuwijk, Andrea Mazzino, Markus Holzner · 2021

Turbulent mixing layers in nature are often characterised by the presence of a mean shear and an unstable buoyancy gradient between two streams of different velocities. Depending on the relative strength of shear versus buoyancy, either th…

Spatially evolving cascades in temporal planar jets Open

Connecting the time evolution of the turbulence interface to coherent structures – CORRIGENDUM Open

Marius M. Neamtu-Halic, Dominik Krug, J.-P. Mollicone, Maarten van Reeuwijk, George Haller , et al. · 2020

The above mentioned article was submitted with incorrect author affiliations for George Haller and Markus Holzner. This has since been rectified in the online PDF and HTML copies. (J. Fluid Mech. (2020) 898 (A3) DOI: 10.1017/jfm.2020.414)

Evolution of the turbulence interface in flows with and without stable stratification Open

Marius M. Neamtu-Halic, Dominik Krug, J.-P. Mollicone, Maarten van Reeuwijk, George Haller , et al. · 2020

The surface area of turbulent/non-turbulent interfaces (TNTIs) is continuously produced and destroyed via stretching and curvature/propagation effects. Here, the mechanisms responsible for TNTI area growth and destruction are investigated …

Turbulence dynamics in separated flows: the generalised Kolmogorov equation for inhomogeneous anisotropic conditions Open

J.-P. Mollicone, F. Battista, P. Gualtieri, Carlo Massimo Casciola · 2018

The generalised Kolmogorov equation is used to describe the scale-by-scale turbulence dynamics in the shear layer and in the separation bubble generated by a bulge at one of the walls in a turbulent channel flow. The second-order structure…

Drag reduction induced by superhydrophobic surfaces in turbulent pipe flow Open

Roberta Costantini, J.-P. Mollicone, F. Battista · 2018

The drag reduction induced by superhydrophobic surfaces is investigated in a turbulent pipe flow. Wetted superhydrophobic surfaces are shown to trap gas bubbles in their asperities. This stops the liquid from coming in direct contact with …

Application of the Exact Regularized Point Particle method (ERPP) to particle laden turbulent shear flows in the two-way coupling regime Open

F. Battista, P. Gualtieri, J.-P. Mollicone, Carlo Massimo Casciola · 2018

Effect of geometry and Reynolds number on the turbulent separated flow behind a bulge in a channel Open

J.-P. Mollicone, F. Battista, P. Gualtieri, Carlo Massimo Casciola · 2017

Turbulent flow separation induced by a protuberance on one of the walls of an otherwise planar channel is investigated using direct numerical simulations. Different bulge geometries and Reynolds numbers – with the highest friction Reynolds…

Energy fluxes in turbulent separated flows Open

J.-P. Mollicone, F. Battista, P. Gualtieri, Carlo Massimo Casciola · 2016

Turbulent separation in channel flow containing a curved wall is studied using a generalised form of Kolmogorov equation. The equation successfully accounts for inhomogeneous effects in both the physical and separation spaces. We investiga…

Turbulent separation in a channel with a curved wall Open

J.-P. Mollicone, F. Battista, P. Gualtieri, Carlo Massimo Casciola · 2015

Flow separation, in both external and internal flows, is the main source of turbulent fluctuations which ultimately results in drag and inefficiency in applications. The basic issue of turbulence self sustainment is still not exhaustively …
