Dynamic thermal analysis of pulsed blue diode pumped Ti:Sapphire amplifiers [PDF]

EPJ Web of Conferences
We simulated the time-dependent temperature profiles inside a blue diode pumped Ti:Sapphire (Ti:Sa) laser amplifier for several different pulsed pump configurations using a discrete element method, including temperature-dependent thermal conductivity and

Bayesian Estimation and Uncertainty Quantification of a Temperature-Dependent Thermal Conductivity

We consider the problem of estimating a temperature-dependent thermal conductivity model (curve) from temperature measurements. We apply a Bayesian estimation approach that takes into account measurement errors and limited prior information of system properties. The approach intertwines system simulation and Markov chain Monte Carlo (MCMC) sampling. We

Fractional heat conduction with variable thermal conductivity in rotating hydro-semiconductors

Scientific Reports
This work introduces a novel framework for analyzing wave propagation in hydro-semiconductors by simultaneously incorporating fractional-order heat conduction, temperature-dependent thermal conductivity, and rotational effects into a unified photo ...

Nonlocal Thermoelasticity Theory for Thermal-Shock Nanobeams with Temperature-Dependent Thermal Conductivity

Journal of Thermal Stresses, 2015
In this work, a model of nonlocal generalized thermoelasticity with one thermal relaxation time is used to consider the vibration behavior of an Euler-Bernoulli (E-B) nanobeam. The thermal conductivity of the nanobeam is assumed to be temperature-dependent.

Numerical Investigation of Transient Heat Conduction through a Thermal Insulation of Temperature Dependant Thermal Properties

Al-Khawarizmi Engineering Journal, 2014
The two-dimensional transient heat conduction through a thermal insulation of temperature dependent thermal properties is investigated numerically using the FVM. It is assumed that this insulating material is initially at a uniform temperature.

Controlling thermal chaos in the mantle by positive feedback from radiative thermal conductivity [PDF]

Nonlinear Processes in Geophysics, 2002
The thermal conductivity of mantle materials has two components, the lattice component klat from phonons and the radiative component krad due to photons.

Geodynamo Conductivity Limits

Geophysical Research Letters, 2019
In a metal, as in Earth's core, the thermal and electrical conductivities are assumed to be correlated. In a planetary dynamo this implies a contradiction: that both electrical conductivity, which makes it easier to induce current and magnetic field, and
