Experimental and simulation results are presented from an investigation of simultaneous heat air and moisture transport in a loose-fill insulation. The aim of the study was to investigate the thermal and moisture effects of natural air convection with no liquid transport present and to validate a numerical model. The structure was placed between two climate chambers at different temperatures. The quasi-steady-state temperature distribution in the cavity of the structure and transient moisture condition were measured, as well as the material properties.
Natural ventilation systems for industrial buildings have traditionally been designed using empirical engineering models, which often require the designer to 'over-engineer' the design to achieve a 'guaranteed' level of ventilation performance. This paper describes an application of computational fluid dynamics (CFD) and multi-zone thermal and airflow modelling to analyse the effectiveness of natural ventilation in removing moisture from a red mud filtration building used in the alumina industry in Australia.
As the thermal sensation of humans depends directly on heat transfer characteristics between the body surface and the surrounding environment, it is very important to clarify the heat transfer characteristics of a human body surface in detail. This paper describes a combined numerical (NOTE I) simulation system of airflow, thermal radiation and moisture transport based on a human thermo-physiological model used to examine the total (sensible + latent) heat transfer characteristics of a body surface. The human body is assumed to be naked (NOTE 2).
