To find in (7) the values of the current or final temperature [[theta].sub.iS] of heating the material of the current-carrying parts of the CCP, determined by Joule heat from the action of the SC current [i.sub.k(t)] on it, we first use the well-known nonlinear dependence of the specific electrical conductivity [[gamma].sub.i] of the material of the core (shell) of the wire or cable on the value of temperature [[theta].sub.iS] [5]:
Highlighting the clean tech benefits of our patented solutions is a crucial component of our stated goals of being the recognized industry leader in using electricity to aggregate particulates in crude (AOT Viscosity Reduction System) and directly heat oil for more efficient flow assurance (STWA Joule Heat).
As a consequence the temperature of the cable can be relatively high even for moderate values of the Joule heat produced in the cable as compared to the same cable in air with natural convection cooling.
In the model it is assumed that all electrical energy is converted to thermal energy by setting the Joule heat fraction to be equal to one.
Analysis includes comparisons of velocity, temperature, Lorentz force, and Joule heat.
The generated joule heat is the heat source for cooking.
A typical situation is under-loading LEA (steady current value below the rated current) and an atmosphere with temperatures below 0[degrees]C, in the presence of wind, the Joule heat developed in the current conduction process leading to a temperature lower than the hoar-frost formation temperature (about -5[degrees]C).
The effect of Joule heat generation at 1 T affects the temperature profile to a lesser extent as the value is of the order of 10- [18].
On the other hand, Joule heat density produced in conventional long carbon fibres (i.e., intermediate modulus fibres, IM) is two orders of magnitude larger than that produced in copper.

By resistance heating this term corresponds to the Joule heat computed by electric analysis.
