Summary:

This paper mainly presents a novel aero-thermal coupled simulation approach for estimating the cooling performance of automotive brakes under the scenario of fading stop cycles. This approach couples the quasi-steady computational fluid dynamics (CFD) analysis in the fluid domain and the transient thermal calculation in the solid domain. An advanced coupling strategy is proposed and applied in the approach especially for analyzing the vented disc brakes, which can solve the problem of boundary mismatch between the fluid and solid domains during the simulation. Moreover, this approach incorporates a Point-in-Polygon (P-in-P) algorithm for a more efficient and accurate calculation of braking heat flux through the brake disc. Such an approach has been implemented on a vehicle model with all the geometry details, and the comparison between the simulation results and the experimental data demonstrates the ability of the approach as an efficient tool to estimate the cooling performance of automotive brakes under the scenario of fading stop cycles. The approach can be applied on different automotive frictional brakes and provide significant guidance for handling overheated brakes
