Abstract Aiming at the uneven temperature distribution of die surface in autoclave process, a simulation method of temperature field in autoclave process has been established based on XFlow software. Unlike the current grid-based computational fluid dynamics software, XFlow uses particle-based lattice Boltzmann method, which effectively shortens the pre-processing time. The finite element model of forced convection heat transfer of frame die in autoclave process is established by XFlow software. The average relative error between the calculated results and the experimental results is 1.83%. The reason of uneven temperature distribution of die surface in the process of forming is analyzed, and the influence of process parameters of autoclave process on the temperature field of die is discussed. The results show that the standard deviation of die surface temperature can be effectively reduced by increasing the wind speed and decreasing the heating and cooling rate.
