, 2017 We present a new experimental set-up that creates a shear flow with zero mean advection velocity achieved by counterbalancing the nonzero streamwise pressure gradient by moving boundaries, which generates plane Couette-Poiseuille flow.

Reconfigurable Acoustofluidic Microvortices for Selective Microcargo Delivery
Advanced Science, EarlyView.This work introduces a frequency‐encoded, reconfigurable acoustofluidic system that overcomes the low throughput and poor selectivity of conventional micro‐delivery methods. By exploiting discrete microbubble resonances to program adaptive microvortex modes, the platform enables real‐time switching and selective guidance of microscale payloads through ...

Modal and nonmodal stability analysis of electrohydrodynamic flow with and without cross-flow [PDF]
, 2015 We report the results of a complete modal and nonmodal linear stability analysis of the electrohydrodynamic flow (EHD) for the problem of electroconvection in the strong injection region.

Experimental methods for wind tunnel studies of seed dispersal by wind
Applications in Plant Sciences, EarlyView.Abstract The complexity and variability of natural environments make quantitative studies of seed wind dispersal challenging. Wind tunnel experiments offer a controlled alternative to investigate the mechanisms of seed wind dispersal. This review focuses on wind tunnels and the associated technologies used for studying seed wind dispersal, including ...

Effects of Poiseuille flow on peristaltic transport
International Journal of Mathematics and Mathematical Sciences, 2001 The effects of Poiseuille flow on peristaltic transport in a cylindrical tube has been investigated. A perturbation solution is obtained, which satisfies the momentum equation for the case in which the amplitude ratio (wave amplitude/tube radius) is ...

Exploiting timescale separation in micro and nano flows [PDF]
, 2011 In this paper we describe how timescale separation in micro/nano flows can be exploited for computational acceleration. A modified version of the seamless heterogenous multiscale method (SHMM) is proposed: a multi-step SHMM.

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations
Deep Underground Science and Engineering, EarlyView.Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.
