Hydroplaning and skid resitance analysis using numerical modeling

The study can be divided into two main stages. This first stage involves hydroplaning simulations using the tire deformation profiles obtained in the experimental hydroplaning studies conducted by the National Aeronautical and Space Administration (NASA). Two- and three-dimensional numerical modeling of hydroplaning are first explored. It is found that a three-dimensional model of hydroplaning with the consideration of turbulent flow is necessary to produce numerical results close to experimental results reported in the literature. A three-dimensional numerical hydroplaning simulation model using computational fluid dynamics is presented. The tire pressure-hydroplaning speed relationship predicted by the model is found to be in close agreement with the NASA hydroplaning equation. The effect of pavement microtexture on hydroplaning is studied using the developed model.
