Heat and Moisture Conduction in Unsaturated Soils [PDF]

open access: yes, 1975
Mathematical models are developed for the prediction of heat transfer from hot water pipes buried in the soil. Heat transfer in the absence of moisture transfer is described as a function of the difference between the temperature of the pipe and the ...

Multiscale modelling for better hygrothermal prediction of porous building materials

open access: yesMATEC Web of Conferences, 2018
The aim of this work is to understand the influence of the microstructuralgeometric parameters of porous building materials on the mechanisms of coupled heat, air and moisture transfers, in order to predict behavior of the building to control and improve

Heat and moisture transfer dynamics in humidity-stratified paddy grain bulk under mechanical ventilation

open access: yesResults in Engineering
Temperature and humidity within grain bulks are two critical factors affecting the safe storage duration of grains. Investigating the heat and moisture transfer mechanisms during storage, along with the coupled interactions among various in-silo factors,

A finite volume-based model for the hydrothermal behavior of soil under freeze-thaw cycles.

open access: yesPLoS ONE, 2021
Freeze-thaw cycles in soil are driven by water migration, phase transitions, and heat transfer, which themselves are closely coupled variables in the natural environment. To simulate this complex periglacial process at different time and length scales, a

Modeling deep-bed grain drying using Comsol Multiphysics [PDF]

open access: yes, 2013
CFD simulations were carried out to predict the convective heat and mass transfer coefficients in the rice bed, and correlations were developed for the convective heat and mass transfer coefficients as a function of drying air flow rate.

Model and experiment of heat and moisture transfer process of exhaust air flow strengthened by wet hydrophobic fiber grid

open access: yesMeitan xuebao
How to approach the limit of heat and humidity energy extraction from exhaust air flow is a difficult problem for low-grade waste heat recovery technology in mines, and the key is to explore new ways to strengthen heat and moisture transfer between gas ...
