In this work, a CFD-based model is proposed to analyse the effect of phase change materials (PCMs) on the thermal behaviour of the walls of a cubicle exposed to the environment and on the resistance of the walls to climate changes. The effect of seve

This paper presents a methodology to simulate the combustion of fixed beds of biomass particles using computational fluid dynamics (CFD) techniques. The models presented were used in the simulation of a domestic pellet boiler working under operating

A ThermoGravimetric Analyser with Differential Scanning Calorimeter (TGA–DSC) was modelled and simulated to evaluate heat transfer to the sample and the internal operation of the equipment. For this purpose, a mesh was generated based on a CAD desi

A solar radiation absorber was simulated with CFD techniques and the results are compared with experimental data. The porous medium was modelled with a dispersed particle approach. Heat transfer of the porous media was calculated separately for a non

This study is conducted to determine, from an energetic point of view, the reasons for the success of Galician granaries (the most important traditional “dry storage” structure, also called a “horreo”, typical in the northwest of Spain). Gran

The present work proposes a novel and alternative FTIR calibration method to quantify gases. Unknown concentrations are deducted from calibration curves, obtained by combining a dilution flow with another flow of the gas of interest. Both streams are

Granaries (horreos) are bioclimatic conservation structures with various forms that have been used for over 2000 years in different countries across Europe and Asia. Galician raised granaries built upon “staddle stones” (pillars with a rodent-pro
