Thermal Characteristics of a Stratospheric Airship with Natural Convection and External Forced Convection

open access: yesInternational Journal of Aerospace Engineering, 2019
Though convective heat transfer is one of the main factors that dominate the thermal characteristics of stratospheric airships, there is no specific correlation equations for the calculation of convective heat transfer of airships. The equations based on

Forced-convection condensation inside tubes [PDF]

open access: yes, 1971
High vapor velocity condensation inside a tube was studied analytically. The von Karman universal velocity distribution was applied to the condensate flow, pressure drops were calculated using the Lockhart- Martinelli method, and heat transfer ...

Dynamic Magnonic Crystals Based on Spatiotemporal Plasmon Excitation

open access: yesAdvanced Materials, EarlyView.
Hybrid magnonic‐plasmonic metamaterials enabling spatiotemporal optical control of spin‐wave transport are demonstrated. These structures integrate periodic stripes of gold nanodisk arrays with low‐damping yttrium iron garnet films to realize dynamically reconfigurable magnonic crystals.

Liquid neon heat transfer as applied to a 30 tesla cryomagnet [PDF]

open access: yes
A 30-tesla magnet design is studied which calls for forced convection liquid neon heat transfer in small coolant channels. The design also requires suppressing boiling by subjecting the fluid to high pressures through use of magnet coils enclosed in a ...

Light‐Fueled In‐Operando Shape Reconfiguration, Fixation, and Recovery of Magnetically Actuated Microtextured Covalent Adaptable Networks

open access: yesAdvanced Materials, EarlyView.
A covalent adaptable network with dynamic disulfide bonds (DS‐CAN) can rearrange its molecular topology through heating or UV irradiation. When combined with ferromagnetic particles, its photoresponsiveness at room temperature enables contactless, spatiotemporal regulation of dynamic bond exchanges during magnetomechanical actuation.
