Abstract
A rain simulation system that replicates realistic raindrop characteristics for controlled testing is invented. The rain simulation system can be used as a stand-alone system with wind using a blower fan or in a wind tunnel, and without wind to create wind-driven and vertically falling rain droplets, respectively. In addition, methods to simulate rainfall for stationary and moving objects such as a road passenger vehicle are proposed. The rain simulation system is fully adjustable for a range of droplet size, impact velocity, rain intensity, rain coverage via the use of dripping nozzle devices and positioning of system components. The rain simulation system dispenses distinct droplets or continuous streams that can be broken down into droplets by wind. A rain nozzle device is coupled with a rain reservoir, and multiple nozzles are used to create a rain matrix, the full matrix is integrated with a rain rack and rainwater flow control strategy.
