Abstract
The intensity of heat removal by convective heat transfer from ventilated brake discs of wheeled vehicles is directly affected by the amount and passage time of the air flow through the ventilation apparatus. The more intense the air flow at the inlet and slower at the outlet to the ventilation unit, the more intensively the cooling of the brake disc will take place. It is possible to slow down the speed of air wind passage by creating artificial obstacles or by switching from laminar to turbulent flow regime. The research methodology proposed in this paper is able to characterize the mechanism of places` formation of high and low pressure in the ventilation duct and the occurrence of vortex flows during the turbulent flow of the air flow.
