The influence of variable thermal conductivity of semiconductor elastic medium during photothermal excitation subjected to thermal ramp type

Results in Physics, 2019
In this article, the photothermal excitation and thermal conductivity of a semiconducting elastic medium due to variable temperature effect are studied. The dual-phase-lag (DPL) model and Lord-Shulman (LS) theory are used to formulate and discuss the one

Response of photo-elasto-electric semiconductor porosity medium according to changing thermal conductivity with two-temperature

AIP Advances, 2023
This study examines a new model for a solid semiconductor porosity medium with variable thermal conductivity under photo-thermoelastic conditions using two-temperature theory. A normal mode analysis is carried out to solve the equations in two dimensions

Variable conductivity in forced convection for a tube filled with porous media: A perturbation solution

Ain Shams Engineering Journal, 2018
In this study, the forced convective in a tube filled with porous media is investigated analytically based on the perturbation methods. Thermal conductivity of the medium is assumed to be a linear function of radius.

Spin-catalyzed hopping conductivity in disordered strongly interacting quantum wires [PDF]

, 2016
In one-dimensional electronic systems with strong repulsive interactions, charge excitations propagate much faster than spin excitations. Such systems therefore have an intermediate temperature range [termed the "spin-incoherent Luttinger liquid'" (SILL)

Solving the heat equation with variable thermal conductivity

Applied Mathematics Letters, 2023
We consider the heat equation with spatially variable thermal conductivity and homogeneous Dirichlet boundary conditions. Using the Method of Fokas or Unified Transform Method, we derive solution representations as the limit of solutions of constant-coefficient interface problems where the number of subdomains and interfaces becomes unbounded.

MHD Flow of Thixotropic Fluid with Variable Thermal Conductivity and Thermal Radiation

Walailak Journal of Science and Technology, 2012
An analysis has been carried out to examine the two-dimensional and magnetohydrodynamic (MHD) flow of thixotropic fluid over a stretched surface. The thermal radiation effect in the heat transfer is considered when the thermal conductivity is not ...
