The effective parameters on Ohmic heating in static system containing biosolid-water were studied. The effects of distribution of particles, salinity and electric field strength on electrical conductivity,</e...

in this article, some diagnostic systems and the preliminary results of the ir-t1** (iran-tokamak 1) are presented. different diagnostic methods, including an array of soft x-ray detectors, visible spectrometer, electron cyclotron emission detector and electromagnetic measurement systems have been used and the hard disruptive instability occurring in the ir-t1 plasma during an ohmic heating dis...

We study a stationary thermistor model describing the electrothermal behavior of organic semiconductor devices featuring non-Ohmic current-voltage laws and selfheating e↵ects. The coupled system consists of the current-flow equation for the electrostatic potential and the heat equation with Joule heating term as source. The self-heating in the device is modeled by an Arrhenius-like temperature ...

From the gross conservation laws of thermodynamics in a convecting material we derive a bound on the ratio of the rate of production of mechanical or magnetic energy to the rate of internal radioactive heating which drives the convection. Our bound for this "efficiency" depends on the temperatures in the material, and can exceed unity. Whether the bound can be attained by "efficiencies" in real...

The high-power heating of magnetic reconnection has been applied to the ultra-high-beta ST formation in the TS-3, TS-4 and UTST merging experiments. Two low-beta ST plasmas were formed inductively by two or four PF coils without using any central solenoid (CS) and were merged for high power MW-GW reconnection heating. Cause and mechanism for the reconnection heating were directly measured for t...
