Hydrodynamic instabilities, waves and turbulence in spreading epithelia

Soft Matter, 2017
We present a hydrodynamic model of spreading epithelial monolayers described as polar viscous fluids, with active contractility and tractions. Our model provides a comprehensive understanding of a variety of observations and makes simple predictions to further test their collective dynamics.

On how structures convey non-diffusive turbulence spreading

Nuclear Fusion
We report on comprehensive experimental studies of turbulence spreading in edge plasmas. These studies demonstrate the relation of turbulence spreading and entrainment to intermittent convective density fluctuation events or bursts (i.e. blobs and holes).

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

The role of shear flow collapse and enhanced turbulence spreading in edge cooling approaching the density limit

Nuclear Fusion
Experimental studies of the dynamics of shear flow and turbulence spreading at the edge of tokamak plasmas are reported. Scans of line-averaged density and plasma current are carried out while approaching the Greenwald density limit on the J-TEXT tokamak.

Multi-Stage Information Spreading Model in Simplicial Complexes Driven by Spatiotemporal Evolution of Public Health Emergency

IEEE Access, 2023
The long cycle and cross-region evolution of the public health emergency have caused sharp turbulence in the society. Especially, the multi-stage and multi-channel information spreading triggered by the public health emergency has further aggravated the ...

How far does turbulence spread?

Journal of Fluid Mechanics, 2023
In this talk I will discuss how turbulence can spread in space in the absence of mean momentum injection. I will present results from direct numerical simulations of a turbulent flow in a long triply periodic box generated by a forcing that is localized in space.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Edge turbulence spreading and blob transport broaden the heat flux width approaching the density limit

Nuclear Fusion
This paper investigates how edge turbulence spreading and blob transport broaden the heat flux width in Ohmic-plasma approaching the operational density limit of the J-TEXT tokamak. At the plasma edge, ${{\boldsymbol{E}}_{\mathbf{r}}} \times {\mathbf{B}}$

MHD instability dynamics and turbulence enhancement towards the plasma disruption at the HL-2A tokamak

Scientific Reports, 2023
The evolutions of MHD instability behaviors and enhancement of both electrostatic and electromagnetic turbulence towards the plasma disruption have been clearly observed in the HL-2A plasmas.

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam

Advanced Engineering Materials, EarlyView.
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.
