A status report of wind-driven rain research at the Laboratory of Building Physics, K.U.Leuven

This paper reports on past and ongoing wind-driven rain (WDR) research at the Laboratory of Building Physics, K.U.Leuven. It is based on the philosophy that WDR research consists of two main parts: (1) The assessment of the amount and intensity of WDR impinging on the building facade and (2) The assessment of the contact and surface phenomena that occur after impact of raindrops: splashing, evaporation, adhesion, absorption, runoff. The paper provides a brief overview of research in terms of full-scale measurements and CFD simulations of WDR on the VLIET test building and full-scale measurements with a newly developed test set-up for contact and surface phenomena.
