Analysis of Internal Flow Field Characteristics of Tire Capsule Vulcanization

In order to reduce the temperature difference caused by condensed water in vulcanized tire capsules, the flow field and temperature field inside vulcanized tire capsules were numerically simulated by setting three different intake angles based onvolume of fluid (VOF) multiphase flow model. When the intake air is blown to the upper and lower tire sides of the vulcanized capsule at 18° from the horizontal direction, the distribution of condensed water at the bottom of the capsule changes obviously due to the effect of vorticity flow, and the distribution along the wall is more uniform. When the inlet air is blown down the tire side, the condensate is most evenly distributed along the wall, and the maximum temperature difference drops to 9.5 ℃. The results show that changing the distribution of condensed water by adjusting the proper intake angle can effectively reduce the temperature difference of condensed water in vulcanized capsules.
