Large contact angle hysteresis enhances post‐impact droplet oscillations
Droplet, Volume 5, Issue 1, January 2026.Contact angle hysteresis (CAH) sustains high‐order droplet oscillations after impact by enabling nonlinear energy transfer between modes, leading to persistent modulated shape dynamics. Abstract Droplet impact on solid surfaces plays a critical role in a wide range of applications, including inkjet printing, spray cooling, surface coatings, and ...

Support Structure Modelling in Actuator Line Method Large Eddy Simulations of Wind Turbine Wakes
Wind Energy, Volume 29, Issue 1, January 2026.ABSTRACT While advancements in the prediction of wind turbine loads and wakes within the actuator line method large eddy simulation (ALM‐LES) framework have been an active research topic in recent years, the modelling of the tower and nacelle has received comparatively less attention.

Design of 3D equilibria and coils for steady-state operation of tokamaks
Nuclear FusionInspired by the respective advantages of tokamaks and stellarators, we propose a quasi-axisymmetric (QA) tokamak-stellarator hybrid concept as a steady-state operation mode of standard tokamaks.

Environmental Research LettersMulti-source observations revealed an atypical double-eyewall structure in Super Typhoon Doksuri (2023), which we define herein as an ‘eccentric eyewall’. Ultimately, the structure evolved into the more familiar concentric eyewall (CE).

Inferring the scrape-off layer heat flux width in a divertor with a low degree of axisymmetry
Nuclear Materials and EnergyPlasma facing components (PFCs) in the next generation of tokamak devices will operate in challenging environments, with heat loads predicted to exceed 10 MW/m2. The magnitude of these heat loads is set by the width of the channel, the ‘scrape-off layer’

Effect of symmetry-breaking on the MHD edge stability limit of tokamak plasmas
Nuclear FusionWe demonstrate for the first time that symmetry-breaking in tokamak plasmas reduces the window of stable edge operational space, leading to a lower achievable edge pressure gradient.

An Investigation on the Effects of Different Stratifications on Negatively Buoyant Jets
EPJ Web of Conferences, 2018 Negatively buoyant jets develop when fluids are released upwards into a lighter fluid or, vice versa, downwards into a heavier fluid. There are many engineering applications, such as the discharge, via submerged outfalls, of brine from desalination ...
