WATER SPRAY CAUSED BY VEHICLES ON WET ROAD

PROJECTIONS D'EAU OCCASIONNEES PAR LES VEHICULES SUR ROUTE MOUILLEE

RESULTS OF NUMEROUS TESTS CARRIED OUT AT THE LUTAC (FRANCE), TRRL AND MIRA (UNITED KINGDOM) AND THE STEVENS INSTITUTE (USA) HAVE SHOWN THAT THERE DOES NOT EXIST AT THE PRESENT TIME A REALLY EFFECTIVE METHOD OF REDUCING THE NUISANCE DUE TO SPRAYS CAUSED BY VEHICLES TRAVELLING ON WET ROADS. TESTS CARRIED OUT WITH PRIVATE CARS IN FRANCE AND OTHER COUNTRIES PROVED THAT RUBBER FLAPS OF VARYING STIFFNESS ARE HARDLY EFFECTIVE ON SOME VEHICLES AND NOT EFFECTIVE AT ALL ON OTHERS. THE PROBLEM REMAINS TO BE SOLVED. IT SEEMS THAT THE FLAPS MUST BE ADAPTED TO EACH TYPE OF CAR BODY, THE PROJECTION AND PULVERISATION DENSITY BEING RELATED, AMONG OTHER THINGS, TO THE AERODYNAMIC SLIP STREAM OF THE VEHICLE.
