Abstract: Hydroplaning phenomenon is one of the major factors that must beconsidered to ensure safe driving on wet road surfaces. In this paper, theapproach to numerical simulation of the physical hydroplaning characteristicsusing patterned tire is described. A detailed 3-D patterned tire model isconstructed by in-house modeling program and the water flow is considered asincompressible. The complex tire material compositions are effectively modeledusing composites, and rubber properties generalize the Mooney-Rivlin model. Thefinite element method (FEM) and the advanced finite volume method (FVM) areused for structural and for fluid-tire interaction analysis, respectively.Performance prediction of hydroplaning via coupling of computational fluiddynamics (CFD) and FEM has delivered a detailed insight into the localmechanisms and root causes of hydroplaning. Numerical examples were verified bycomparing the experimental test results and it is confirmed to indicate similarcorrelation tendency and high reliability. The effect of driving velocity,pattern groove size, and pattern direction on hydroplaning phenomenon of tireis discussed and logical results were obtained.
