Self-inhibiting heat flux [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
Heat-transfer through weakly magnetized diffuse astrophysical plasmas excites whistlers. This leads to electron whistler resonant scattering, a reduction of the electron mean-free path, and heat-flux inhibition. However, only whistlers propagating at a finite angle to the magnetic field (off-axis) can scatter the heat-flux carrying electrons. Thus, the

Numerical simulation and experimental investigation of bubble behaviour during pool boiling in the coiled wire

open access: yesHeliyon, 2023
Under the computational fluid dynamics (CFD) framework, an interface tracking method has been used to perform several multiple simulations of coiled wire boiling in a pool.

Modeling of Heat Flux in a Heating Furnace

open access: yesComputation, 2023
Modern heating furnaces use combined modes of heating the charge. At high heating temperatures, more radiation heating is used; at lower temperatures, more convection heating is used. In large heating furnaces, such as pusher furnaces, it is necessary to monitor the heating of the material zonally. Zonal heating allows the appropriate thermal regime to

Research On Maximizing Critical And Reducing Initial Heat Flux Densities To Eliminate Any Film Boiling And Minimize Distortion During Quenching [PDF]

open access: yes, 2017
In the paper the results of testing three types of FUCHS oils: Thermisol QH 120, Thermisol QH 10 and Thermisol QB 46 are discussed. The main attention is paid to critical heat flux densities evaluation because they create a basis for optimizing cooling ...

Heat flux solarimeter

open access: yesSolar Energy, 2010
Abstract The solarimeter presented in this work is easy to assemble. It is calibrated and its performance is validated by means of Hottel’s method ( Hottel, 1976 ). Finally, the curves obtained with this solarimeter are compared to the ones obtained with a commercial solarimeter. This device is based on the evaluation of the heat flow in a metal rod.

Inflation driven by causal heat flux [PDF]

open access: yes, 1997
We find a simple inflationary solution in an inhomogeneous spacetime with heat flux. The heat flux obeys a causal transport equation, and counteracts the inflationary decrease of energy density.

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 ...

Flow boiling in a 1.1mm tube with R134a: Experimental results and comparison with model [PDF]

open access: yes, 2007
A detailed comparison of the three-zone evaporation model, proposed by Thome et al. (2004), with experimental heat transfer results of two stainless steel tubes of internal diameter 4.26 mm and 2.01 mm using R134a fluid was presented by Shiferaw et al ...

A Mariotte-based verification system for heat-based sap flow sensors [PDF]

open access: yes, 2012
Determination of the accuracy of commonly used techniques for measuring sap flux density in trees often presents a challenge. We therefore designed and built a verification system for heat-based sap flow sensors typically used at stem level.
