Joule heating at high latitudes

Journal of Geophysical Research: Space Physics, 1983
High latitude Joule heating has been calculated from simultaneous observations of the electric field magnitude and the Pedersen conductivity calculated from individual measurements of the ion drift velocity and particle precipitation observed over the lifetime of the AE‐C satellite.

Electromagnetism and Joule Heating

2010
Joule heating was one of the first non-equilibrium processes studied as thermodynamics developed in the first half of the nineteen century. The Carnot caloric theory that heat is a substance dominated thought in 1850, but Joule argued that heat is vibration and so is a dynamic process.

Joule Heating in Rectangular Conductors

Journal of Thermal Science and Engineering Applications, 2020
Abstract Analytic solution for nonuniform internal Joule heating in a wire of rectangular cross section is obtained. The eigenvalues for convective or weak radiative boundary conditions are accurately estimated by asymptotic expansions. The problem is governed by the aspect ratio, the convection parameter β, and a nonuniform parameter α ...

Joule heating and particle precipitation

Advances in Space Research, 1982
Abstract A short review of different techniques for deriving the amount of heat input into the auroral upper atmosphere due to Joule heating and particle precipitation is given. The relative importance and altitude of these two energy sources with respect to auroral substorm time is stressed.

The ineffectiveness of Joule heating in the stratosphere

Journal of Atmospheric and Solar-Terrestrial Physics, 2010
Several papers have recently invoked Joule heating in the stratosphere, generated from electric currents induced by solar wind interactions with Earth, as possibly playing a significant role in warming the polar stratosphere. This commentary assesses the accuracy of that contention and demonstrates that in situ Joule heating can take no significant ...

Joule heating at the magnetic equator

Planetary and Space Science, 1963
Joule heating of electrons and ions at the magnetic equator, where intense electric current flows, is discussed. It is shown that the power generated is between 10/sup -8/ and 10/sup -7/ erg cm/sup -3/ sec/sup -1/ and that the electron temperature is raised above the neutral particle temperature by several tens of deg K. This temperature increase could

Coupled Effects: Joule-Heating

2012
Heterogeneous microstructures lead to a distortion of the electrical and current field within the material mixture. This leads to the fields becoming amplified within the material, which can lead to a variety of detrimental effects. An important quantity of interest is the amount of heat generated from an electrical field.

Joule heating in the photosphere and chromosphere

Journal of Geophysical Research: Space Physics, 1989
Joule dissipation due to the dynamo action in the solar atmosphere is proposed as a possible mechanism for heating the photosphere and chromosphere. In nonactive regions, Joule heating is distributed in both photosphere and chromosphere. The power density (ergs cm−3 s−1) produced by the Joule dissipation in the nonactive photosphere‐chromosphere ...
