Abstract
It is shown that heat energy transfer from the
source to the medium is accompanied by rheological
transitions. Physical parameters of the medium change in
the rheological transition zone due to heat energy flow
transfer at a certain speed. It is shown that use of linear
gradient laws during description of heat energy transfer
processes leads to great differences between theoretical
and experimental results, as well as the paradox of
infinite spreading speed of disturbances of temperature
fields. For mathematical description of heat energy
transfer processes in mediums, it is proposed to use the
method of irreversible rheological transitions and zero
gradient, thus providing solutions of nonlinear
differential equations in analytical form.
