摘要：

The braking network of an automobile is one of its most important control systems. For many years, disc brakes have been used for safe retardation of a vehicle. During braking, an enormous amount of heat is generated, and for effective braking, sufficient heat dissipation is essential. The thermal performance of a disc brake depends on characteristics of the airflow around the brake rotor; hence, aerodynamics is key in the region of brake components. Using ANSYS CFX software, we performed a computational fluid dynamics (CFD) analysis on a brake system to study the behavior of airflow distribution around disc brake components. We were interested in the determination of the heat-transfer coefficient on each surface of a ventilated disc rotor, varying with time in a transient state. Using CFD analysis, we imported surface film condition data into a corresponding finite-element method for disc temperature analysis.
