The ANSYS Fluent software is used in a 2D simulation to predict the heat transfer coefficient and the flow fields.
First, the CFD software tool ANSYS Fluent was used to simulate each parameter and based on the simulation results several improved parameters were selected to make a mockup sample.
Based on the results of the simulation, the four types of designs that were used for the divergent structure are displayed in Figure 8.

From the simulation results, it was found that tire width has a noticeable effect on tire-pavement noise.
Tire-Pavement Noise Simulation Model Fig. 1 shows the geometry of tire pavement noise simulation, which consists of two sub-models: the tire-pavement interaction sub-model and the near-field sound propagation sub-model.
However, for a proper simulation of sound, air compressibility must be considered within the large eddy simulation (LES) model.
