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.
