Abstract

Ventilated brake disk is the state of the art technology in automobile braking system. It is well known that the braking capability of brake disk is affected by the rate at which heat is dissipated through forced convection. The rapid increase and decrease of the brake disk temperature could lead to catastrophic failure of the brake disk due to high thermal stress. The objective of the current study is to investigate the potential heat transfer enhancements in ventilated brake disk by varying the geometrical parameters of the blades inside the flow passage. This is done through comparisons of non-dimensional properties for flow and heat transfer in different blade configurations of the ventilated brake disk. The straight blade configuration is used as a baseline reference against the angled blades. The investigations are performed by using both experimental and computational means and the results are compared and discussed. Analysis shows that significant increase in braking performance can be achieved with relatively simple alteration of the ventilated blade angle. The results show a tremendous increase in the heat transfer rate with blade inclination angle configurations as compared to conventional straight blade. The Nusselt number is found to be in a power-law relationship with the Reynolds number. Distinct relationship between laminar and turbulent condition is predicted. An improvement in total convective heat transfer coefficient of 51% was achieved with blade inclination angle of 45° tilting towards clockwise direction.
