We revisit the effects of Joule heating upon the upper atmospheres of Jupiter and Saturn. We show that in addition to direct Joule heating there is an additional input of kinetic energy − ion drag energy − which we quantify relative to the Joule heating. We also show that fluctuations about the mean electric field, as observed in the Earth’s ionosphere, may significantly increase the Joule heat...

Saltwater intrusion into coastal aquifers presents a significant global challenge to fresh groundwater resources. Numerical modelling represents valuable tool study this phenomenon. Darcy’s Law is widely applied studies and extended the Brinkman Equation account for kinetic dissipations due viscous shear. However, their comparative performance accuracy in density-driven flows remain unclear. To...

Stereoselective dissipation of epoxiconazole had been studied in grape and soil during plant growing under field conditions in this paper. A sensitive and rapid chiral method was developed and validated for the determination of epoxiconazole stereoisomers in grape and soil based on liquid chromatography coupled with triple quadrupole mass spectrometry (LC-MS/MS). Phenomenex Lux Cellulose-1 colu...

The analysis in this communication addresses the unsteady MHD flow of tangent hyperbolic liquid through a vertical plate. model on mass and heat transport is set up with Joule heating, generation, viscous dissipation, thermal radiation, chemical reaction Soret-Dufour form partial differential equations (PDEs). PDEs are simplified into dimensionless by utilizing suitable quantities. solved spect...

An electric field was applied to a conductive layer to induce Joule heating in order to generate the intense heat needed to carry out the crystallization of amorphous silicon. Complete crystallization was observed via Joule heating under typical processing conditions. Crystallization was accomplished throughout the sample within the range of microseconds of the heating, thus demonstrating the p...

This article deals with the thermal convection in a dielectric fluid confined in a finite-length plane capacitor with a temperature gradient under microgravity conditions. The dielectrophoretic force resulting from differential polarization of the fluid plays the role of buoyancy force associated with an electric effective gravity. It induces the convection when the Rayleigh number based on thi...
