We have performed direct numerical simulations of a spatio-temporally intermittent flow in a pipe for Rem = 2250. From previous experiments and simulations of pipe flow, this value has been estimated as a threshold when the average speeds of upstream

On Mars, large aeolian ripples with wavelengths typically 1-3 m but lacking very coarse sand at crests have been encountered by rovers and observed from orbit. These bedforms have no terrestrial counterpart and several hypotheses for origins have bee

We have performed direct numerical simulations of a transitional flow in a pipe for \(Re_m=2250\) when turbulence manifests in the form of fleshes (puffs). From experiments and simulations, \(Re_m \approx 2250\) has been estimated as a threshold when

Small-scale turbulence measurements in liquid metals are generally conducted using potential difference probes (PDPs). However, the use of PDPs in alternating magnetic field-driven flows is limited as the driving magnetic field (DMF) induces a noise

The limits of the axisymmetric ideal inductor approach and the low magnetic Reynolds number (Rem) approach are demonstrated for the case study of a flow driven by a rotating magnetic field induced by an explicit-pole non-ideal inductor. These effects

High-resolution three-dimensional simulations (involving 100 million degrees of freedom) were employed to study transient turbulent flow in a carotid arterial bifurcation with a stenosed internal carotid artery (ICA). The geometrical model was recons

Proper orthogonal decomposition (POD), Kriging interpolation, and smoothing are applied to reconstruct gappy and noisy data of blood flow in a carotid artery. While we have applied these techniques to clinical data, in this paper in order to rigorous

An immersed-boundary method was employed to perform a direct numerical simulation (DNS) of flow around a wall-mounted cube in a fully developed turbulent channel for a Reynolds number Re = 5610, based on the bulk velocity and the channel height. Inst

An approximation of function u(x) as a Taylor series expansion about a point x0 at M points xi , ∼i = 1, 2, . . . ,M is used where xi are arbitrary-spaced. This approximation is a linear system for the derivatives u with an arbitrary accuracy. An a
