Abstract. This paper mainly focuses on the numerical simulation of temperature field in the cyclone separation. The authors took advantage of RSM turbulence model of software FLUENT to imitate the temperature field. This thesis puts forward the temperature distribution of the cyclone, and figures out that the overall temperature is 373°C. Temperature difference in different region is less than one centigrade degree with the maximum temperature in the cone part and the minimum temperature in inlet tube and cylinder part of the cyclone, what’s more, the temperature is relatively higher near the wall. The air compression can lead the higher temperature in the lower part, so the cone part has the highest temperature. The higher temperature near the wall is caused by the friction between the wall and flow. Introduction This paper mainly focuses on the flow field phenomenon of gas-solid separation process in CLT/A type cyclone separator about the potato granules drying system. The simulation is established based on the discrete coupling model, the assumption of which is that the model needs the constant temperature. It is really necessary to simulate the temperature field of CLT/A type cyclone as the temperature of hot air is relati
