This technical note presents a coupled thermo-hydromechanical model for unsaturated soil, which can be applied in the context of high temperature. A new pore gas or bulk air transfer equation is introduced. Additionally the effect of temperature on the latent heat of vapourisation and specific heat capacities is incorporated. Adsorbed water is also included. The performance of the model is demo...

Molecular diffusion processes are caused by concentration gradients in a multi-component mixture. Noticeable diffusion flux can also be induced by temperature gradients which lead to partial separation of constituent components. This cross effect between temperature and concentration is known as thermo diffusion or Soret effect. This effect can be quite important in the analysis of the distribu...

This work reports the results of the theoretical investigation of nonlinear dynamics and spiral wave breakup in a generalized two-variable model of cardiac action potential accounting for thermo-electric coupling and diffusion nonlinearities. As customary in excitable media, the common Q10 and Moore factors are used to describe thermo-electric feedback in a 10° range. Motivated by the porous na...

We proposed a general formulation of the successive linearization method for solving highly nonlinear boundary value problem arising in rotating disk flow. The problem was studied under the effects of partial slip, thermal diffusion, and diffusion-thermo. The governing fundamental conservation equations of mass, momentum, angular momentum, energy, and concentration are transformed into a system...

The effects with a variable temperature and mass diffusion are obs...

This article explores the heat and mass transfer behaviour of magnetohydrodynamic free convective flow past a permeable vertical rotating cone and a plate filled with gyrotactic microorganisms in the presence of nonlinear thermal radiation, thermo diffusion and diffusion thermo effects. We presented dual solutions for the flow over a rotating cone and a rotating flat plate cases. Similarity var...

We study the solvability and homogenization of a thermal-diffusion reaction problem posed in a periodically perforated domain. The system describes the motion of populations of hot colloidal particles interacting together via Smoluchowski production terms. The upscaled system, obtained via twoscale convergence techniques, allows the investigation of deposition effects in porous materials in the...

mechanical stress and maximum superconducting current have been calculated for a superconductor subjected to uniform plastic deformation. The training effect due to strain hardening o f the material is discussed. These results are compared with an analogous case when the normal transition is caused by the thermo-magnetomechanical instability. The quenching current is shown to depend on the hist...
