Exactly one year ago I presented my full scale experimental campaign on the Nordic Symposium on Building Physics. Since then I’ve been analysis the results further and in a couple of weeks the final paper should be finished. Below a short summary of the preliminary results of the campaign.
Today I gave a seminar at our research group reporting the progress in my phd on runoff of wind-driven rain on porous building materials. The main focus of the presentation was on the experimental work I conducted in 2013 with a little wink to the simulation work I’m doing now with OpenFOAM. The latter however is still a marvellous discovery of the power of OpenFOAM at the moment, but results are expected soon. Below you can find the abstract and presentation of the seminar.
As wind-driven rain is one of the most important moisture sources for a building envelope, a reliable prediction of the wind-driven rain load is a prerequisite to assess the durability of a building facade. To incorporate wind-driven rain in HAM models (heat, air and moisture), many factors should be taken into account. Not only building geometry, wind speed and wind direction, raindrop size distribution, etc. influence the rain load on buildings, but also phenomena such as raindrop impact, absorption, evaporation and runoff should be taken into account. The following is an excerpt from ‘influence of facade materials on runoff due to wind-driven rain’ by T. Van den Brande et al (2012). A full text is available upon request.
