NOISE MANAGEMENT STUDY OF A CAR’S COOLING SYSTEM
The article presents a comparative study of four radiator fans with different blade numbers. The four simulations were conducted at different speeds for each fan, in such a way, that the tonal noise caused by the blade passing frequency has the same value in each case. As a result, the discharged air flow rates of the four fans were analyzed and compared.
