Optimization of a Laboratory Rainfall Simulator to Be Representative of Natural Rainfall

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