Reconnection and Disconnection: Observations of Suprathermal Electron Heat Flux Dropouts [PDF]

open access: yes, 2010
Suprathermal electron heat flux dropouts (HFD) serve as a sensitive test of the magnetic topology of the inner heliosphere. Since the heat flux electron strahl always flows away from the Sun, a heat flux dropout should indicate either that the magnetic ...

Heat flux in a granular gas [PDF]

open access: yesAIP Conference Proceedings, 2012
A peculiarity of the hydrodynamic Navier-Stokes equations for a granular gas is the modification of the Fourier law, with the presence of an additional contribution to the heat flux that is proportional to the density gradient. Consequently, the constitutive relation involves, in the case of a one-component granular gas, two transport coefficients: the

Analytical modeling for the heat transfer in sheared flows of nanofluids [PDF]

open access: yes, 2012
We developed a model for the enhancement of the heat flux by spherical and elongated nano- particles in sheared laminar flows of nano-fluids. Besides the heat flux carried by the nanoparticles the model accounts for the contribution of their rotation to ...

Experimental Study of Heat Flux Distribution of Arc Driven by AC Magnetic Field

open access: yesAdvances in Materials Science and Engineering, 2011
The authors earlier developed a model to predict the heat flux distribution in an arc driven by an AC magnetic field. That theoretical model implied that the heat flux distribution depended on waveforms of the imposed AC magnetic field.

Experimental Study on the Flow Boiling Heat Transfer Characteristics in a Mini-Channel with Offset Fins

open access: yesProceedings, 2018
The present study studied the flow boiling heat transfer performance of a mini channel with offset fins experimentally. The hydraulic diameter for it is 1.59 mm with 9 offset rectangular channels. The influences of saturation pressure, mass flux and heat

Effect of Inhomogeneous Heat Flow on the Enhancement of Heat Capacity in Helium-II by Counterflow near Tλ [PDF]

open access: yes, 2006
In 2000 Harter et al. reported the first measurements of the enhancement of the heat capacity ΔCQ[equivalent]C(Q)-C(Q=0) of helium-II transporting a heat flux density Q near Tλ.

Air-Sea Heat Flux Variability in the Southeast Indian Ocean and Its Relation With Ningaloo Niño

open access: yesFrontiers in Marine Science, 2019
Previous studies suggest that both air-sea heat flux anomalies and heat advection caused by an anomalous Leeuwin Current play an important role in modulating the sea surface temperature (SST) variability associated with the Ningaloo Niño.

Numerical Investigation of Heat Transfer in Garment Air Gap

open access: yesAUTEX Research Journal, 2020
This article aimed to study the characteristics and mechanisms of 3D heat transfer through clothing involving the air gap. A three-dimensional finite volume method is used to obtain the coupled conductive, convective, and radiative heat transfer in a ...
