An Intelligent Microfluidics Enabled by Data‐Driven Deep Learning‐Based Microrobot‐Assisted Flow Manipulation

Advanced Intelligent Systems, EarlyView.
An AI‐enabled micromixing framework is developed by integrating cGAN with Bayesian optimization for predictive control of microrobot‐driven flow manipulation. Through this framework, the spatiotemporal evolution of micromixing is learned directly from experimental images, while rapid identification of optimized microrobot actuation strategies is ...

X-Ray imaging method for in-situ study of particle-laden flows

e-Journal of Nondestructive Testing
 The accurate measurement of flow parameters often depends on sensor accessibility. Optical flow assessment techniques, such as Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV), are limited to optically transparent media. However,

Particle Image Techniques for Measuring Instantaneous Bed Shear Stress in Open Channel Flows

工程科学与技术, 2022
Measurement of instantaneous bed shear stress in open channel flows is challenging but extremely important. In order to accurately measure the instantaneous bed shear stress with particle image techniques, synthesized particle images with different image

Low‐Field MRI as a Multiparametric Tool for Large Engineered Tissue Characterization

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Advances in 3D bioprinting have enabled the fabrication of large and complex engineered tissues, but their increasing size demands non‐invasive tools for monitoring structure, maturation, and perfusion. Magnetic Resonance Imaging (MRI) offers unique multiparametric capabilities, yet high‐field systems remain costly and inaccessible for most ...

Particle Image Velocimetry in practice

, 2009
Experimental fluid mechanics has for a long time been used to visualize flow phenomenon. An early pioneer was Ludwig Prandtl who used aluminum particles in water flumes to describe the flow in a qualitative manner. In line with the rapid development of Computational Fluid Dynamics, CFD, the need for new validation tools has increased.

Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

Chemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Labeling Strategies for Monitoring Cytoskeleton Dynamics in Cultured Epithelial Cells

Cytoskeleton, EarlyView.
ABSTRACT Collective cell migration relies on coordinated cytoskeletal remodeling, yet the impact of live‐cell actin filament probes on these dynamics remains poorly characterized. Here, we systematically compared the performance and cellular effects of fluorogenic jasplakinolide‐based probes, SiR‐actin and SiR‐XActin, with the genetically encoded ...
