Electron Heat Fluxes Generated by Intense Whistler Waves at the Upper Ionospheric Altitudes

Journal of Geophysical Research: Space Physics, 2022
AbstractMagnetospheric whistler waves, chorus and hiss, can't provide the resonance heating of the core electron plasma population. However, these whistler‐mode branches, can implicitly participate in the heating processes of the core plasma thermal electron population by triggering the electron precipitation over a broad energy range from the ...

Flux Sensor Measurement and Calibration Requirements for High-Intensity Heat Flux Applications

SolarPACES Conference Proceedings
Stakeholders of CSP and non-CSP high-intensity broadband flux measurements were surveyed and interviewed to obtain flux sensor design and calibration requirements. Existing sensor technologies and existing calibration facilities were then compared against this standard.

Thermal Conductivity of PNIPAm Hydrogels and Heat Management as Smart Windows

Macromolecular Materials and Engineering, 2023
Though thermoresponsive lower critical solution temperature (LCST) hydrogels have attracted intense attention to be applied in smart windows, less efforts are paid on the LCST effect on the heat transfer process.

Hurricane's maximum potential intensity and surface heat fluxes

, 2018
Emanuel's concept of Maximum Potential Intensity (E-PI) relates the maximum velocity $V_{\rm max}$ of tropical storms, assumed to be in gradient wind balance, to environmental parameters. Several studies suggested that the unbalanced flow is responsible for E-PI sometimes significantly underpredicting $V_{\rm max}$.

Study of the heat flux fluctuations intensity during flow around a circular cylinder

Journal of Physics: Conference Series, 2021
Abstract An experimental study performed in an air channel using gradient heatmetry is presented, for a configuration of three heated circular cylinders with different distance between them. Cylinders were installed one by one. The main objective is to analyze the heat flux fluctuations, employing gradient heat flux sensor.

Constraining the properties of neutron star crusts with the transient low-mass X-ray binary Aql X-1 [PDF]

, 2015
Aql X-1 is a prolific transient neutron star low-mass X-ray binary that exhibits an accretion outburst approximately once every year. Whether the thermal X-rays detected in intervening quiescent episodes are the result of cooling of the neutron star or ...

Ablation behavior studies of charring materials with different thickness and heat flux intensity

Case Studies in Thermal Engineering, 2021
Surface ablation and in-depth temperature distribution of the charring material are the key properties of the thermal protection system in re-entry vehicles subjected to aerodynamic heating. To investigate the factors affecting the ablation performance of charring materials, the influence of decomposition reaction and surface recession on ablation was ...

Warm‐air advection, air mass transformation and fog causes rapid ice melt [PDF]

, 2015
Direct observations during intense warm-air advection over the East Siberian Sea reveal a period of rapid sea-ice melt. A semi-stationary, high-pressure system north of the Bering Strait forced northward advection of warm, moist air from the continent ...
