• Abstract

The ventilated disc brake rotor with vane passages formed between braking surfaces; acts as a centrifugal fan and facilitates the required air flow for cooling. To improve the performance of a ventilated disc brake rotor, selection of proper geometrical configuration is more important. Disc brake rotor with different geometrical configurations were analyzed for flow analysis. Numerical modelling can predict flow characteristics & can serve as an efficient design tool. Hence it has been used for making modifications in the existing rotor geometry vane passages and which will consequently contribute for better flow development. A CFD code has been employed for theoretical analysis which will determine the distribution of pressure and velocity vectors in the flow field. Numerical results for mass flow rate have been validated experimentally. The selection of disc brake rotor configuration for breaking application has been discussed based on the obtained results.

Keywords: Ventilated Disc Brake Rotor, CFD, and Vane shape.
