Research on Cooling Simulation of Drum Stirrer Based on CFD
With a drum mixer as the research object,a CFD(Computational Fluid Dynamics)software was used to perform simulation analysis.Through steady-state simulations,the influence of cooling air flow rate on the cooling effect was investigated.Orthogonal simulation experiments were conducted to assess the impact of three factors—inlet particle temperature,total air flow rate,and the proportion of cooling air to the inner wall—on the cooling effect.The analysis results revealed that when the total cooling air flow rate is greater than or equal to 50m3/h,the equipment can achieve a cooling target below 50℃.Particle temperature and air flow rate were identified as the most significant factors influencing the cooling efficiency of the equipment.Furthermore,when the cooling time exceeds 50s,the material can reach a cooling equilibrium.Based on these findings,the process parameters for the drum mixer's operation were optimized,providing insights for structural design improvements and enhancing the equipment's operational efficiency.
