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 CommunicationsHigh 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 ...

Periodically Modulated Thermal Convection [PDF]
Physical Review Letters, 2020 Many natural and industrial turbulent flows are subjected to time-dependent boundary conditions. Despite being ubiquitous, the influence of temporal modulations (with frequency $f$) on global transport properties has hardly been studied. Here, we perform numerical simulations of Rayleigh-Bénard (RB) convection with time periodic modulation in the ...
