Heat and moisture transfer in concrete slabs

International Journal of Heat and Mass Transfer, 1979
Abstract To predict the moisture distribution in concrete slabs as functions of time, the dependence on the relevant material characteristics must be considered. The phenomena relevant for moisture, pressure, and temperature distribution are coupled.

Heat and Moisture Transfer in Building Enclosing Structures

2021
Nowadays, there are various mathematical models which give an opportunity to determine the moisture distribution inside building walls. It has to be stated that some models calculate steady-state moisture transportation in the capillary-porous media, while other models assess unsteady-state moisture movements.

Heat and Moisture Transfer in 3D Garment CAD

2008 Second International Symposium on Intelligent Information Technology Application, 2008
This paper presents the results of an extensive literature review on the topic of heat and moisture transfer in 3D Garment CAD. The adaptive approach to modeling heat and moisture transfer process through fabric. An important premise of the model is that includes physical process, liquid and vaporpsilas phase change, and capillary effects.

Heat and moisture transfer from trimmed glasshouse crops

Agricultural Meteorology, 1964
Abstract Trimmed crops of cotton, beans and saltbush were grown in a glasshouse, and measurements made of the radiation flux, soil heating and evapotranspiration rate. The energy-balance equation then yielded the sensible-heat flux between a crop and the air above, so that measurements of leaf and air temperatures gave the heat-transfer coefficient ...

Heat and moisture transfer in ventilated grain

Journal of Agricultural Engineering Research, 1966
The various processes concerned with heat and moisture transfer in deep beds of grain have been classified. It was found that at high air humidities and grain moisture contents the existing thin layer drying theory is inadequate. Despite the shortcoming of the existing theory, a system of equations and a numerical step by step solution for predicting ...

Heat and moisture transfer in sol–gel treated cotton fabrics

Journal of Thermal Analysis and Calorimetry, 2012
Cotton fabrics have been treated by sol–gel processes in order to produce an inorganic coating on fibres, able to modify their thermal conductivity under an irradiating flow. To this aim, fabric specimens with different silica content have been tested following the ISO 6942 standard in order to establish the effect of the coating on coupled heat and ...

Heat and moisture transfer through cold-store walls

Batiment International, Building Research and Practice, 1981
The building of an experimental cold-store at a commercial growers' premises in the UK provided an opportunity to measure the behaviour of vapour barrier and insulation in a working setting. The bitumastic vapour barrier was found not to prevent migration of water vapour ; it is therefore suggested that a practical solution would be to design for the ...

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.

Simultaneous Heat, Moisture and Salt Transfer in Clothing

2008
Sweat is important for the response of human body in the thermal environment. It is usually simplified as pure water when the influence of sweat on the human body temperature is studied for the prediction and evaluation of the thermal comfort. However sweat is, in reality, salt water with low concentration.

Finite element program for moisture and heat transfer in heated concrete

Nuclear Engineering and Design, 1982
Abstract A new axisymmetric finite element program for the analysis of pore pressure, moisture content and temperature in heated concrete is described. The program is based on the diffusion equations for coupled heat and moisture transfer and uses a step-by-step time integration. The finite element scheme is based on Galerkin method.
