In the present work, different ventilated disc brake rotor configurations were analysed to enhance the heat transfer rate and obtain the uniform temperature distribution in the rotor. CFD code used in this work was validated at using experimental results obtained by conducting experiments on a test rig. The experimental analysis was performed to calculate the mass flow rate and heat dissipation through the rotor. Further, different types of rotor configurations viz. straight radial vane (SRV), tapered radial vane (TRV), alternate long and short vane (ALSV), variable diameter circular pillars (VDCP) were considered for the analysis. A rotor segment of 20° was considered for the numerical analysis due to its rotational symmetry. CFD results were in good agreement with the experiments. The maximum deviation of the numerical results were about 12 % from the experimental results. It is found from the analysis that among the different types of rotor configurations; variable diameter circular pillars (VDCP) rotor gives better rate of heat dissipation with more uniform temperature distribution in the flow passages. Hence for modern high speed vehicles VDCP rotor may be more appropriate. © 2017, The Korean Society of Automotive Engineers and Springer-Verlag Berlin Heidelberg.

Experimental investigation using CFD for thermal performance of ventilated disc brake rotor

In the present work, different ventilated disc brake rotor configurations were analyzed to enhance the heat transfer rate and obtain the uniform temperature distribution in the rotor. CFD code used in this work was validated using experimental results obtained by conducting experiments on a test rig. The experimental analysis was performed to calculate the mass flow rate and heat dissipation through the rotor. Further, different types of rotor configurations viz. straight radial vane (SRV), Tapered radial vane (TRV), Alternate long and short vane (ALSV), variable diameter circular pillars (VDCP) were considered for the analysis. A rotor segment of 20° was considered for the numerical analysis due to its rotational symmetry. CFD results were in good agreement with the experimental analysis. The maximum deviation of the numerical results were about 12% from the experimental results.

Experimental analysis and investigation for thermal performance of ventilated disc brake rotor using CFD

In the present work, ventilated disc brake rotors with variable diameter circular pillar configurations were analyzed to enhance the heat dissipation and obtain more uniform temperature distribution in the rotor. CFD code used in this work was validated with experimental results obtained by conducting experiments on a test rig. Experimental analysis was performed on existing taper radial vane (TRV) rotor to calculate the mass flow rate and heat transfer coefficient. Further, variable diameter circular pillar (VDCP) rotor with different configurations namely VDCP1, VDCP2 and VDCP3 were considered for the analysis. A 20° segment of rotor was considered for the numerical analysis due to its rotational symmetry. CFD results were in good agreement with the experimental analysis. The maximum deviation of numerical results were about 15% from the experimental results. It is found from the analysis that among all the rotor configurations; VDCP1 rotor configuration gives better rate of heat dissipation and more uniform temperature distribution in the rotor. Hence for modern high speed vehicles VDCP1 rotor configuration may be more appropriate. © 2016 IEEE.
