【 摘 要 】

Introduction: the objective of this study was to analyze the behavior of the temperature, velocity and heat flow in the ventilation duct of three brake disc designs using computational fluid dynamics (CFD). Methods: the design software SolidWorks was used for the analysis. The three disc designs differed in geometry and application. The numerical results for the flow of heat through the ventilation channels were compared with mathematically obtained results. Results: the numerical results showed that the discs performed well under severe operating conditions (80 Km/h and an ambient temperature of 22°C). It is very important in brake disc design to select the appropriate geometry, particularly the number and the cross section of the ducts, and the type of material. Conclusions: numerical methods offer advantages for selecting the geometry and the material and for modeling the fluid flow to optimize the heat dissipation to provide the maximum performance for properly maintained components.
