1. Introduction. In the linear range a general theory of thermoelasticity based on irreversible thermodynamics was developed and discussed extensively in some earlier work ([3], [4], [9]). It was assumed that the elastic solid is initially in a stress-free equilibrium state at uniform temperature. Completely linearized perturbations in the vicinity of this equilibrium state are then analyzed as...

Today, the focus of physical scientists is shifting more to biology than ever before. A biological tissue is typically an ionised porous medium saturated with a solution of ions and neutral solutes. Because classical porous media theories do not account for ionisation, the present paper addresses this issue. The characteristic pore size in most biological applications is close to the molecular ...

In this paper, a novel iterative coupling scheme is developed for solving coupled hydro-mechanical problems using reproducing kernel particle method. The numerical scheme calls the fluid and the solid solvers sequentially and iteratively until convergent solutions are obtained. To overcome the numerical instability problem, a simple stabilization technique is developed and proved to be uncondit...

An analysis is conducted to investigate the problem of heat/mass transfer in MHD free convective flow Casson-fluid a vertical channel embedded with saturated porous medium past through carbon nanotubes form single-wall (SWCNTs) and multiple-wall (MWCNTs) engine oil as base fluid. In this article, impact CNT’s on velocity, temperature, shear stress rate heat nanofluid has been investigated studi...

We report theoretical and numerical studies of the flow behaviour when a fluid is injected into a confined porous medium saturated with another fluid of different density and viscosity. For a two-dimensional configuration with point source injection, a nonlinear convection–diffusion equation is derived to describe the time evolution of the fluid–fluid interface. In the early time period, the fl...

Air entrainment is commonly used to improve the durability of concrete materials exposed to freezing and thawing. While the influence of air voids on freeze/thaw damage and salt scaling is frequently studied, the influence of entrained air voids on ionic transport has been studied less frequently. Since ionic transport in concrete materials relies on pore fluid as the medium of conduction, only...

This paper discusses a new nuclear magnetic resonance (NMR) method that can provide wettability, saturation, and oil viscosity values in rocks partially saturated with oil and brine. The method takes advantage of two new technological advances in NMR well logging—the MRF* Magnetic Resonance Fluid Characterization Method and NMR “diffusion-editing” (DE) pulse sequences. We discuss the principles...

Numerical modeling of seismic response soil deposits is usually conducted as part hazard assessment, preceding facility construction in any tectonically active regions, including offshore sites. A significant feature subsea soils their porous and water-saturated structure. Thus, the purpose present study to introduce a procedure for nonlinear behavior porous, moist during SH-wave propagation, v...

Various biological and chemical processes lead to the nucleation growth of non-wetting fluid bubbles within pore space a granular medium, such as formation gas in liquid-saturated lake-bed sediments. In sufficiently soft porous materials, nature these can result open cavities solid skeleton. Here, we consider this process through lens phase separation, where thermomechanics govern separation fr...
