A Simulation Model for Coupled Heat Transfer and Moisture Transport under the Action of Heat Source in Unsaturated Soils

Analysis of coupled heat and moisture transfer in masonry structures

Evaluation of effective or macroscopic coefficients of thermal conductivity under coupled heat and moisture transfer is presented. The paper first gives a detailed summary on the solution of a simple steady state heat conduction problem with an emphasis on various types of boundary conditions applied to the representative volume element – a periodic unit cell. Since the results essentially sugg...

heat and contaminant transport in unsaturated soil

solute transport in unsaturated porous media can be viewed as a coupled phenomenon with waterand heat transport, together with mechanical behaviour of media. in this paper, solute transport is formulatedmathematically considering heat and water flow in deformable porous media. advection, dispersion anddiffusion of chemical species in the liquid phase are considered. convection and conduction fo...

Heat transfer in MHD nanofluid flow over a cone and plate in the presence of heat source/sink

In this study, we presented a mathematical model for analyzing the heat source/sink effect on magnetohydrodynamic two-dimensional ferrofluid flow past a cone and a vertical plate in the presence of volume fraction of ferrous nanoparticles. The governing partial differential equations are transformed as ordinary differential equations making use of similarity solutions and solved numerically wit...

Modeling of Coupled Moisture and Heat Transfer During Wood Drying

Development of an accurate mathematical model of sufficient generality to evaluate drying processes in materials having diverse moisture transport properties is proposed. The process of wood drying is interpreted as simultaneous heat and moisture transfer with local thermodynamic equilibrium at each point within the timber. The model is a mathematical one treating wood as a continuous and homog...
