Aero-thermal analysis of ventilated passage in a brake disc 2020-28-0011

In this paper, the numerical investigation of a brake disc is done for studying its aero-thermal behaviour and finding alternatives that perform better. In a disc brake, the heat generated due to friction has to be dissipated by one or the other modes of heat transfer. Out of the three modes of heat transfer, convection is to be maximized as others may cause deterioration of neighbouring parts. The disc is of ventilated type and hence the turbulence and mass flow rate through this ventilated area is to be optimized so as to improve the convective heat transfer coefficient. An in-depth study of various design changes previously done for improving heat transfer coefficient in ventilated disc is done and these changes are incorporated in the existing design. Various design combinations using different design tweaks for improving heat transfer coefficient are made and simulated in component testing like conditions, which are validated against previously done actual experiments. Total of 12 different design iterations were simulated and the one with the highest heat transfer coefficient was analysed in detail.
