Séminaire exceptionnel IUSTI

Numerical methods for predicting heat and moisture transfer through porous building materials

Orateur : Suelen Gasparin – Postdoctotal Researcher, LaSIE, La Rochelle

Abstract : In the current environmental context, it is essential to know how to model the phenomena of heat and mass transfer through porous elements of buildings walls. Therefore, the objective of this seminar is to present innovative numerical methods to efficiently simulate hygrothermal transfer phenomena. First, we describe the physical model and we introduce the scientific issues associated with the development of the numerical models. Then, we present several improved numerical methods applied to real case studies, such as multilayered-walls with nonlinear transfer, parametric problems, optimum insulation thickness, moisture buffer effect and zonal building model. Particularly, a reduced-order model based on spectral methods is presented for the simulation of multidimensional transfer. A comparison with experimental data is also carried out. To summarize, a global overview of the discussed numerical methods is proposed.

Date et lieu : jeudi 8 octobre à 14h en salle 250 à l’IUSTI
