Full-scale measurements and numeric simulations of driving rain on a building

Results of full-scale measurements and c.f.d. simulations of driving rain on a building facade and of wind at one position at 0.5 m from the facade surface, along with reference measurements, are presented. The wind is simulated by a standard K-εmodel, and the results are compared with measurements quantitatively and qualitatively. The applied model of driving rain takes drop trajectories and raindrop spectra into account. The simulated driving rain is compared with 10-min measurements of driving rain.
