Coupled heat and moisture transfer in multi-layer building materials

Construction and Building Materials, 2009
A dynamic mathematical model for simulating the coupled heat and moisture migration through multilayer porous building materials was proposed. Vapor content and temperature were chosen as the principal driving potentials. The discretization of the governing equations was done by the finite difference approach.

Coupled heat air and moisture transfer in building structures

International Journal of Heat and Mass Transfer, 1997
Abstract Based on the energy, mass and linear momentum conservation laws as well as the entropy law, a coupled, partial, non-linear, differential equation system for the heat, air and moisture transfer in porous materials follows, and for the more-dimensional solution of it, a suitable algorithm including the simulation software has been developed ...

Coupled Heat and Moisture Transfer During Microwave Vacuum Drying

Journal of Microwave Power and Electromagnetic Energy, 1997
A general mechanistic model has been developed to describe the coupled heat and moisture transfer during dielectrically-assisted drying of porous materials. The model considers the moisture transfer as the combination of the liquid water and vapor water transfer that takes place simultaneously.

Coupled heat and moisture transfer and evaporation in mulched soils

CATENA, 2017
Abstract Improving water efficiency in arid and semi-arid regions is an ongoing goal in agricultural production. Straw mulching is one cultural practice which can be used to this point. Mulch layers associated with the atmospheric condition can create a variety of water and heat flux conditions at the soil surface.

Coupled Heat and Moisture Transfer in Two Common Walls

2013
In order to optimize building energy consumption, it is essential to reduce the heat losses and gains through the building envelope by selecting proper materials which are often porous. However, heat transfer and moisture transfer are often highly coupled, so coupled heat and moisture transfer in two common walls (aerated concrete wall and red brick ...

Ground-Coupled Heat and Moisture Transfer From Buildings: Part 1 — Analysis and Modeling

Solar Engineering 2001: (FORUM 2001: Solar Energy — The Power to Choose), 2001
Abstract Ground-heat transfer is tightly coupled with soil-moisture transfer. The coupling is threefold: heat is transferred by thermal conduction and by moisture transfer; the thermal properties of soil are strong functions of the moisture content; and moisture phase change includes latent heat effects and changes in thermal and ...

Coupled heat and mass transfer during moisture exchange across a membrane

Journal of Membrane Science, 2013
Abstract Coupled heat and moisture transfer through a membrane was modeled and analyzed. Two air fluids flow on each side of the membrane, with one fluid having a higher temperature and a higher humidity ratio than the other, causing a simultaneous heat and moisture transfer across the membrane.

Measurement of Coupled Heat and Moisture Transfer Coefficients for Selected Vegetables

Drying Technology, 1997
ABSTRACT Two experimental devices. Capped Column and Open Column, were used to measure four heat and mass transfer coefficients of four vegetables: potato, yam. butterquash and turnip. Two classical coefficients, thermal conductivity. KT, and moisture diffusivity. DM, and two coupled coefficients. moisture gradient induced heat transfer coefficient, KM,
