Resumen
[EN] The importance of understanding the effects of rainfall on different materials over time
makes it essential to carry out controlled tests to reduce analysis time. Rainfall simulators have been
in use for decades and have been implemented as technology and knowledge of the physical behavior
of water advanced. There are two main types of rainfall simulators: gravity simulators and pressure
simulators. In the former, the drop velocity is normally smaller than the terminal velocity reached by
natural droplets; in the latter, the drop size is too small to be representative and has far more speed
than the natural speed for those sizes. To solve this problem, a simulator has been developed where
the terminal velocity of the raindrops is reached and the drop size can be varied by different nozzles
of variable sizes, adapting it to the conditions of a given region. In this study, conditions similar
to the rainfall conditions of the city of León have been achieved. This paper presents the design of
a rainfall simulator that recreates different rainfall conditions and rainwater composition and its
calibration process.
