Physics of secondary flow phenomenon and erosion characteristics in the injector of a Pelton turbine

open access: yesEngineering Applications of Computational Fluid Mechanics
The Pelton turbine is widely used in the development of high-head hydraulic resources. However, in high-altitude mountainous regions, multiple sediment environments, along with secondary flows generated within the cross-sections of the turbine's ring and

Dynamic flow distortion investigation in an S-duct using DDES and SPIV data [PDF]

open access: yes, 2016
The dynamic flow distortion generated within convoluted aero-engine intakes can affect the performance and operability of the engine. There is a need for a better understanding of the main flow mechanisms which promote flow distortion at the exit of S ...

RENAL‐CHIP: Rejection Evaluation via Non‐Invasive Analysis of Circulating Podocytes With Herringbone‐Chip Isolation Platform

open access: yesAdvanced Science, EarlyView.
RENAL‐CHIP converts 1 mL of peripheral blood into a biopsy‐equivalent readout of renal‐allograft fate. By magnetic capture and release of donor‐derived circulating podocytes through a herringbone microfluidic chip, 84% capture, 96% release and single‐cell RNA evidence of rejection‐specific immunity are achieved.

Vortices determine the dynamics of biodiversity in cyclical interactions with protection spillovers [PDF]

open access: yes, 2015
If rock beats scissors and scissors beat paper, one might assume that rock beats paper too. But this is not the case for intransitive relationships that make up the famous rock-paper-scissors game.

Numerical and Experimental Study of Mixing Characteristics in a Spiral Micromixer

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Significant enhancement of mixing performance can be achieved by Dean vortices in spiral channels. In order to deeply explore the mixing mechanisms and variation laws in spiral micromixers, this work designed a spiral micromixer and adopted a combined method of experiments and numerical simulations to analyze the mixing performance and ...

Design of experiments‐guided membrane capture facilitates integration of continuous virus inactivation using Phi6 as a surrogate virus in an intensified downstream process

open access: yesBiotechnology Progress, EarlyView.
Abstract The growing demand for cost‐efficient and flexible biomanufacturing has increased interest in process‐intensified downstream platforms. This study evaluates an intensified monoclonal antibody (mAb) purification sequence, where two unit operations traditionally performed in batch mode—Protein A capture and low pH virus inactivation (VI)—are ...

Numerical Study of Heat Transfer Enhancement Using Nano-Encapsulated Phase Change (NPC) Slurries in Wavy Microchannels

open access: yesFluids
Researchers have attempted to improve heat transfer in mini/microchannel heat sinks by dispersing nano-encapsulated phase change (NPC) materials in base coolants. While NPC slurries have demonstrated improved heat transfer performance, their applications
