摘要：

This study is part of an ongoing research project investigating the airflow and heat transfer of different disc brake rotors. This article reports on three geometries: straight radial vane (SRV) rotor; SRV rotor with rounded vanes (SRV-R); and a rotor with diamond and teardrop pillars (DTDP) instead of vanes. The total heat transfer from the SRV-R and DTDP passages is up to 20% greater than that for the SRV rotor. As much as 35% more heat is lost from the free side friction surface than the hub side friction surface. Flow development through the DTDP rotor passages is also noted.
