Sub-Millimeter-Scale Measurement of Local Convective Heat Transfer Coefficient Exceeding 100 W/(m^2-K) Using an Optical Pump-Probe Method [PDF]
Measurement, 249 (2025) 117001Conventional methods for measuring the local convective heat transfer coefficient (h_c) often rely on simplifying assumptions that can compromise accuracy. Pump-probe methods like time-domain thermoreflectance (TDTR) avoid these assumptions but are limited to h_c values larger than 30 kW/(m^2-K) due to modulation frequency constraints.

Heat Transfer between Graphene and Amorphous SiO2 [PDF]
arXiv, 2010 We study the heat transfer between graphene and amorphous SiO2. We include both the heat transfer from the area of real contact, and between the surfaces in the non-contact region. We consider the radiative heat transfer associated with the evanescent electromagnetic waves which exist outside of all bodies, and the heat transfer by the gas in the non ...

Transient microscopy for measuring heat transfer in single cells [PDF]
arXiv, 2019 Heat transfer and dissipation exists in almost any physical, chemical or biological systems. Cells, as the basic unit of life, undergo continuous heat transfer and dissipation during their metabolism. The heat transfer and dissipation within cells related to not only fundamental cellular functions and biochemical reactions, but also several important ...

Thermal characterization of convective heat transfer in microwires based on modified steady state "hot wire" method [PDF]
arXiv, 2019 The convection plays a very important role in heat transfer when MEMS work under air environment. However, traditional measurements of convection heat transfer coefficient require the knowledge of thermal conductivity, which makes measurements complex.

Heat Transfer between Weakly Coupled Systems [PDF]
arXiv, 2010 We study the heat transfer between weakly coupled systems with flat interface. We present simple analytical results which can be used to estimate the heat transfer coefficient. As applications we consider the heat transfer across solid-solid contacts, and between a membrane (graphene) and a solid substrate (amorphous SiO2).
