【摘要】 将导热微分方程热源项与橡胶热物性参数视为硫化度与温度的相关函数，建立传热与硫化的耦合计算方程，并基于C语言编写UDF子程序，对FLUENT软件进行二次开发，实现了传热与硫化的耦合计算。模拟结果表明，靠近管壁的外层胶很快到达硫化温度，而靠近管芯的内层胶到达硫化温度需要较长时间，存在明显的温度梯度。当硫化进行到一定时间后，胶管截面各部位温度差异逐渐减小，各部位温度几乎相同，此时胶管各层的传热达到平衡状态。更多还原

【Abstract】 The heat source term of the differential equation of thermal conductivity and the rubber thermophysical parameters were regarded as the correlation function of the vulcanization degree and temperature, and a coupled calculation equation of heat transfer and vulcanization was established.Based on C language, UDF subroutines were written, and FLUENT software was further developed to achieve coupling calculation of heat transfer and vulcanization.The simulation results show that the outer layer of the adhesive near the tube wall quickly reaches the vulcanization temperature, while the inner layer of the adhesive near the tube core takes a long time to reach the vulcanization temperature, and a clear temperature gradient exists.After a certain period of vulcanization, the temperature difference in each section of the rubber hose gradually decreases, and the temperature in each section is almost the same.At this point, the heat transfer in each layer of the rubber hose reaches an equilibrium state.更多还原
