Rain Impact on a Curved Surface High-rise Building

Abstract

ABSTRACT: A Particle Tracking Method is used in conjunction with steady state simulations to determine the trajectories and the impact of rain drops on the curved façade of a high-rise building. The simulation is performed for the upper part of the building comprising a detailed louver system. Rain is trapped at relative high rates on the roof and the penthouse, with Local Intensity Factors (LIF's) of the order of 1. The upper parapets and upper floors get a fair amount of wetting with LIF's of the order of 0.6. The wetting decreases downwards reaching values of 0.2 to 0.25 at the level of the louver system
