Estimating surface temperature in forced convection nucleate boiling: A simplified method [PDF]

open access: yes
During a test program to investigate low-cycle thermal fatigue, 21 of 22 cylindrical test sections of a cylindrical rocket thrust chamber were thermally cycled to failure. Cylinder liners were fabricated from OFHC copper, Amzirc, and NARloy-Z.

Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions

open access: yesAdvanced Materials Interfaces, EarlyView.
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...

Boiling incipience and convective boiling of neon and nitrogen [PDF]

open access: yes
Forced convection and subcooled boiling heat transfer data for liquid nitrogen and liquid neon were obtained in support of a design study for a 30 tesla cryomagnet cooled by forced convection of liquid neon.

Numerical Analysis and Prediction of Unsteady Forced Convection over a Sharp and Rounded Edged Square Cylinder

open access: yesJournal of Applied Fluid Mechanics, 2016
An unsteady two-dimensional forced convection over a square cylinder with sharp and rounded corner edge is numerically analyzed for the low Reynolds number laminar flow regime.

Solvent‐Free Phase Separation of Polystyrene‐block‐poly(2‐hydroxyethyl methacrylate) Forming Freestanding Photonic Films

open access: yesAdvanced Materials Interfaces, EarlyView.
This work presents a scalable, eco‐friendly approach to forming microstructured block copolymer (BCP) films within 15 min through hot pressing. This process enables phase separation even for high‐molecular‐weight BCPs, which are often trapped in spherical structures using time‐consuming solvent processes.
