Abstract: Abstract Suspended particles can significantly alter the fluid properties and, in particular, can modify the transition from laminar to turbulent flow. We investigate the effect of heavy particle suspensions on the linear stability of the… read more here.

Abstract: The high Reynolds-number structure of the laminar, chaotic and turbulent attractors is investigated in a two-dimensional Kolmogorov flow. The laminar attractors include the families of multi-phased travelling waves and quasi-periodic standing waves both of which… read more here.

DOI: 10.1063/1.5013060
Abstract: In this paper, we perform comparative studies of compressible Kolmogorov flow in the two-dimensional strongly coupled dusty plasma by means of atomistic or molecular dynamics (MD) and continuum or computational fluid dynamics (CFD) methods. Recently,… read more here.

DOI: 10.1088/1873-7005/abfaf0
Abstract: Linear and non-linear inertial stability of a Kolmogorov flow in a rotating viscous fluid of uniform density is investigated using the method of continued fractions and the low-order Galerkin approximations. A necessary condition for instability… read more here.

DOI: 10.1103/physreve.96.063112
Abstract: We have found that in two-dimensional Kolmogorov flow a spatially localized turbulent state (SLT) exists stably and travels with a constant speed on average switching the moving direction randomly and intermittently for moderate values of… read more here.
