Large-area silica aerogel for use as Cherenkov radiators with high refractive index, developed by supercritical carbon dioxide drying [PDF]
The Journal of Supercritical Fluids 110 (2016) 183, 2016 This study presents the development of large-area (18 $\times $ 18 $\times $ 2 cm$^3$), high refractive index ($n \sim $1.05) hydrophobic silica aerogel tiles for use as Cherenkov radiators. These transparent aerogel tiles will be installed in a Cherenkov detector for the next-generation accelerator-based particle physics experiment Belle II, to be ...

Subcritical and supercritical bifurcations in axisymmetric viscoelastic pipe flows [PDF]
J. Fluid Mech. (2021), vol. 929, A16, 2021 Axisymmetric viscoelastic pipe flow of Oldroyd-B fluids has been recently found to be linearly unstable by Garg et al. Phys. Rev. Lett., 121.024502 (2018). From a nonlinear point of view, this means that the flow can transition to turbulence supercritically, in contrast to the subcritical Newtonian pipe flows.

Modelling mass transfer from a packed bed by fluid extraction [PDF]
International Journal of Heat and Mass Transfer, Volume 188, 1
June 2022, 122562, 2022 A mathematical model describing the erosion or leaching of a solid material by a flowing fluid in a column is developed. This involves an advection-diffusion equation coupled to a linear kinetic reaction describing the mass transfer between the solid and fluid.
