Lagrangian based thermal conduction

A Shape Memory Alloy Based Cryogenic Thermal Conduction Switch

Shape memory alloys (SMAs) can produce large strains when deformed (e.g., up to 8%). Heating results in a phase transformation and associated recovery of all the accumdated strain. This strain recovery can occur against large forces, resulting in their use as actuators. Thus an SMA element can integrate both sensory and actuation fitnctions, by inhercEtly s e x k g a c h m ~ c ia temperature an...

The Role of Thermal Conduction in Accretion Disks with Outflows

In this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. We study a two-dimensional advective accretion disc in the presence of thermal conduction. We find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. We show that the global structure of an advec...

Evaluation of thermal conduction anisotropy on Thermal Barrier Coating

The microstructural analysis of Thermal Barrier Coatings, deposited according to the Air Plasma Spray technology, furnishes information according which a strong orthotropic thermal conductivity is expected to be measured for such a material. Pulsed experiment with a localized heating source and thermographic temperature recording, permit to evaluate both the in-depth and in-plane components of ...

Thermal Conduction in Simulated Galaxy Clusters

We study the formation of clusters of galaxies using high-resolution hydrodynamic cosmological simulations that include the effect of thermal conduction with an effective isotropic conductivity of 1/3 the classical Spitzer value. We find that, both for a hot (Tew ≃ 12 keV) and several cold (Tew ≃ 2 keV) galaxy clusters, the baryonic fraction converted into stars does not change significantly wh...
