Abstract— Most of the disc brake failures concerning the rotor are mainly due to the overheating. Therefore, it is paramount to enhance the heat dissipation of the ventilated disc brake rotor so that it lasts longer and also functions efficiently. Over the past few years many researchers have come up with innovative designs to address this concern by the analysis of both flow and heat transfer characteristics inside a ventilated brake disc rotor. There are other factors such as weight, thickness of the rotor and sometimes even the number of blades in a rotor that keep changing with the requirement of the car manufacturer. So, there is a huge need within the disc brake manufacturing community for sensitivity analysis data so that heat dissipation and temperature uniformity can be maximized in spite of having some parameters fixed. The main aim of this CFD analysis is to study and predict the effect of various design parameters on the aero-thermal performance of a disc brake rotor.A commercial vehicle of 9.6T is considered for calculation.

I. INTRODUCTION

Disc type brake development and its use began in England in the 1890s. Disc brakes were patented by Frederick William Lanchester in 1902 but the commercial use of these brakes started in the early 1950s [1].The brake disc is the rotating part of a wheel’s disc brake assembly, against which the brake pads are applied. The design of the discs varies somewhat. Some are simply solid, but others are hollowed out with fins or vanes joining together the disc’s two contact surfaces the weight and power of the vehicle determines the need for ventilated discs. The “ventilated” disc design helps to dissipate the generated heat and is commonly used on the more-heavily loaded front discs. Discs have holes or slots cut through the disc for better heat dissipation, to aid surface-water dispersal, to reduce noise, to reduce mass.
