DOI: 10.1007/s00162-017-0421-5
Abstract: The presence of a finite tangential velocity on a hydrodynamically slipping surface is known to reduce vorticity production in bluff body flows substantially while at the same time enhancing its convection downstream and into the… read more here.

DOI: 10.1007/s10714-017-2264-1
Abstract: We point out (and then apply to a general situation) an unusual relationship among a variety of null geodesic congruences; (a) the generators of ordinary light-cones and (b) certain (related) shear-free but twisting congruences in… read more here.

Abstract: Abstract Anisotropies of rotation of inertia-free spheroidal particles have been studied by means of invariants of a rotation correlation tensor. Anisotropy invariant maps (AIMs), supplemented by flatness and axisymmetry parameters F and A, represent a… read more here.

Abstract: This work investigates the role of shear and turbulent fluctuations on multi-species biofilm growth. The study is mostly motivated by understanding biofouling on microplastics (MPs) in oceanic environments. By increasing particle stickiness, biofilms promote MP… read more here.

DOI: 10.3390/e24050645
Abstract: The equation yxx=f(x)y2+g(x)y3 is the charged generalization of the Emden-Fowler equation that is crucial in the study of spherically symmetric shear-free spacetimes. This version arises from the Einstein–Maxwell system for a charged shear-free matter distribution.… read more here.
