Summary on Grant Application Form |
|
The central focus of this project is the identification, quantification and specification of the coupled effect of temperature gradient on the moisture transmission behaviour of building materials, which is currently an area of considerable uncertainty. A current EPSRC-funded project has identified two possible components of this effect: a primary thermodiffusion effect and a secondary effect due to the temperature-dependent nature of permeability, particularly in the important high humidity regime. In order to allow the separation of these components, an extensive experimental programme will be undertaken, consisting of small-scale isothermal permeability tests carried out over a range of test temperatures (10C-10C) and large-scale moisture flow tests carried out under gradients in both temperature and humidity. Eight representative building materials will be studied. The experimental results will be used to develop a mathematical methodology, based on the differential permeability approach, which will allow both primary and secondary nonisothermal effects to be accounted for in moisture flow calculations. In parallel with this, a theoretical framework will be developed for a computer simulation model, again based on differential permeability. This will lead to the generation of a new computer prediction package which is comprehensive in its treatment of the moisture transport process.
