Transition mechanisms in hypersonic wind-tunnel nozzles: a methodological approach using global linear stability analysis

open access: yesFlow
Base-flow computations and stability analyses are performed for a hypersonic wind tunnel nozzle at a Mach number of 6. Isothermal and adiabatic wall boundary conditions are investigated, and moderate stagnation conditions are used to provide ...

Data-driven modelling for on-demand flow prescription in fan-array wind tunnels

open access: yesFlow
Fan-array wind tunnels are an emerging technology to prescribe wind fields through grids of individually controllable fans. This design is especially suited for the turbulent, dynamic, non-uniform flow conditions found close to the ground, and has ...

Breast cancer-secreted miR-939 downregulates VE-cadherin and destroys the barrier function of endothelial monolayers [PDF]

open access: yes, 2017
Exosomes-secreted microRNAs play an important role in metastatic spread. During this process breast cancer cells acquire the ability to transmigrate through blood vessels by inducing changes in the endothelial barrier.

Vortices produced by swirl-mixing grids in nuclear fuel assembly: a wind-tunnel experiment

open access: yesFlow
Longitudinal vortices produced by a swirl-mixing grid are experimentally explored in an upscaled model of nuclear fuel assembly. The flow is mapped using particle image velocimetry in several planes downstream of the grid.
