The onset of double diffusive convection in a viscoelastic fluid-saturated porous layer is studied when the fluid and solid phase are not in local thermal equilibrium. The modified Darcy model is used for the momentum equation and a two-field model is used for energy equation each representing the fluid and solid phases separately. The effect of thermal non-equilibrium on the onset of double di...

In this work, we set forth a multiscale non-equilibrium molecular dynamics (MS-NEMD) model. The main objectives of MS-NEMD model are: (1) establishing a rigorous NEMD that provides direct threedimensional simulations of thermal–mechanical motions at atomistic scale, and (2) providing a general computational paradigm for non-equilibrium multiscale simulations. The proposed MS-NEMD combines a coa...

Constituents of living or synthetic active matter have access to a local energy supply that serves to keep the system out of thermal equilibrium. The statistical properties of such fluctuating active systems differ from those of their equilibrium counterparts. Using the actin filament gliding assay as a model, we studied how nonthermal distributions emerge in active matter. We found that the ba...

Local thermal equilibrium (LTE) is a frequently-employed hypothesis when analysing convection heat transfer in porous media. However, investigation of the non-equilibrium phenomenon exhibits that such typically not true for many circumstances as rapid cooling or heating, and industrial applications involving immediate transient response, leading to lack local (LTE). Therefore, sake appropriatel...

in a temperature gradient, see Fig.1. This is of our knowledge the first molecular dynamics study of a reacting system submitted to non-equilibrium conditions. The reaction, which is diffusion controlled, was investigated at and close to local chemical equilibrium. The transport properties are determines; i.e. diffusion, thermal conductivity and the coupling between transport of heat and mass. ...
