Methods of experimental study of thermal convection in cavity subject to rotation and vibration [PDF]

MethodsX, 2019
Vibrations of a non-isothermal fluid result in the generation of an averaged flows – “thermal vibrational convection”. The effect of vibrations changes qualitatively, and their effectiveness increases significantly under conditions of rotation.

On Transformation Form-Invariance in Thermal Convection. [PDF]

Materials (Basel), 2022
Over the past two decades, effective control of physical fields, such as light fields or acoustics fields, has greatly benefited from transforming media. One of these rapidly growing research areas is transformation thermotics, especially embodied in the thermal conductive and radiative modes.

Integrity of Newton’s cooling law based on thermal convection theory of heat transfer and entropy transfer [PDF]

Scientific Reports, 2022
Although thermal convection is omnipresent in nature and technology and serves important purposes in various energy transport systems, whether convection can be viewed as an independent heat transfer means has long been argued The constant coefficient in

Convection enhanced phase change composite fibers for advanced thermal management [PDF]

Nature Communications
High heat fluxes challenge electronic thermal management, as phase change materials (PCMs) suffer from low heat transfer efficiency. In this work, we present a convection enhanced strategy using molten phase transport in phase change composites (PCCs ...

Thermoelectric convection in a planar capacitor: theoretical studies and experiments in parabolic flights

Comptes Rendus. Mécanique, 2023
Thermoelectric convection in a plane capacitor is investigated in a microgravity environment and in the case of the thermal stable and unstable stratification in terrestrial conditions.
