Taking the standard size coal block samples defined by ISRM as research objects, both properties of methane diffusion of coal block under triaxial compressive stress and characteristic influences caused by methane pressure were systematically studied with thermo-fluid-solid coupling with triaxial servocontrolled seepage equipment of methane-containing coal. The result shows the methane diffusio...

The transient optical response of multiresonant all-dielectric nanoantennas via a combination broadband ultrafast reflectivity experiments and nonlinear optics nanoscale modeling is studied. Ultrafast all-optical control the demonstrated in variably sized Al .18 Ga .82 As over four distinct Mie resonances (including Fano-like resonances), spanning broad spectral range, from red to near-infrared...

These set of notes describe cavity optomechanics in the presence of additional thermo-optic tuning of the cavity resonance. We find that thermo-optic tuning results in correction factors to both the optical spring and optomechanical gain. In addition there is an overall saturation of the optomechanical coupling. These effects can be large for systems with large static thermo-optic tuning and fa...

Abstract: Neutron irradiation plays an important role in nuclear-induced degradation for concrete shielding materials, specifically determining the radiation induced volume expansion (RIVE) phenomenon driving its failure. When analyzing at structural level effects of nuclear on concrete, a non-uniformed distribution neutron must be considered. This can done via particle transport calculations p...

Comparatively little attention has been given to multicomponent diffusion effects in lean hydrogen-air flames, in spite of the importance of these flames in safety and their potential importance to future energy technologies. Prior direct numerical simulations either have considered only the mixture-averaged transport model, or have been limited to stabilized flames that do not exhibit the ther...

In this paper, the effect of various parameters on out-of-phase thermo-mechanical fatigue (OP-TMF) lifetime of A356.0 cast aluminum alloy is investigated. The studied parameters include maximum temperature, dwell time, and the thermo-mechanical loading factor. OP-TMF tests are conducted considering realistic running conditions of diesel engine cylinder heads. The maximum temperature varies betw...
