Journal ArticleDOI
Drag reduction induced by superhydrophobic surfaces in turbulent pipe flow
TL;DR: In this article, a well-defined texture with streamwise grooves at the walls in which the gas is expected to be entrapped is considered, and a substantial drag reduction is observed which strongly depends on the grooves' dimension and on the solid fraction, i.e., the ratio between the solid wall surface and the total surface of the pipe.
Journal ArticleDOI
Dynamics of PIV seeding particles in turbulent premixed flames
TL;DR: In this article, the authors proposed the flamelet Stokes number, a parameter that depends on particle properties and thermochemical conditions of the flame and substantially restricts the particle dimensions required for reliable estimate of the relevant flow statistics.
Journal ArticleDOI
Turbulence dynamics in separated flows: the generalised Kolmogorov equation for inhomogeneous anisotropic conditions
TL;DR: In this article, 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.
Journal ArticleDOI
Effect of geometry and Reynolds number on the turbulent separated flow behind a bulge in a channel
TL;DR: In this article, the effect of the wall curvature and the Reynolds number on the dynamics of the recirculating bubble behind the bump is investigated using direct numerical simulations, revealing a non-trivial behaviour of the energy fluxes.
Journal ArticleDOI
Application of the Exact Regularized Point Particle method (ERPP) to particle laden turbulent shear flows in the two-way coupling regime
TL;DR: In this article, the Exact Regularized Point Particle (ERPP) method was used to explore the response of homogeneous shear turbulence in the presence of different particle populations.
