Wheeler Propagator of the Lorentz Invariant Thermal Energy Propagation

International Journal of Theoretical Physics, 2010
In this paper the authors discussed the Lorentz invariant thermal energy propagation in the field theory of dissipative transport processes, in which the temperature field satisfies a covariant field equation of a (wave like) thermal energy propagation with finite speed-less than the speed of light in contract to the usual local equilibrium temperature

Thermal-neutron propagation in moving media

Physical Review A, 1988
Energies, wave vectors, and amplitudes of waves that are generated when a neutron is incident onto a moving parallel-sided plate are calculated by solving Schroedinger's equation. It is shown that the wave entering the plate and those reflected at the plate surfaces suffer energy (frequency) changes due to ''inelastic'' interaction with the moving ...

Thermal Propagation Control Using a Thermal Diffusion Equation

IEEE Transactions on Industrial Electronics, 2018
Controlling heat flow is necessary in many fields, such as the communications, health care, and manufacturing industries. In the communication field, the techniques for the reproduction of thermal sensations have been researched for many years. In order to extend the area of controlling the heat, the thermal diffusion in time and space needs to be ...

Propagation of Thermal Energy

2014
Usually, measurements are adversely affected by several influence factors, and adequate efforts have to be spent to control environmental conditions. We explain how it is possible to keep thermal fluctuations and thermal gradients around the X-ray interferometer less than 1 mK/h and 10 μK/cm, respectively.
