Experimental characterization of the dynamic thermal properties of opaque elements under dynamic periodic solicitation
MetadataShow full item record
A modified hotbox facility has been used at the Free University of Bozen-Bolzano to measure heat fluxes under a periodic pulse solicitation for some timber structures with different number and kind of layers. The simplest one – a single layer timber structure, has also been modelled with ANSYS Fluent® and the results compared to the experimental data for validation. Then, the numerical model has been used to study different forcing signals and boundary conditions. In order to characterize the response to a periodic dynamic solicitation with simple indexes, the EN ISO 13786:2007 (CEN, 2007) dynamic parameters have also been calculated.
