| Abstract: | A mathematical model that describes the spray drying process for producing ceramic microsphere is proposed based on the analyses of mass-and heat-transfer processes. The corresponding boundary conditions of the model are also determined. The Fluent software is then used to simulate the size and moving trace of the spraying particles. By comparing the calculated results with the tested ones, suitable operation parameters of the spray drying process are finally determined. When the inlet temperature of air is 573 K, the outlet temperature of exhaust gas is 388 K, and the outlet pressure of exhaust gas is -350Pa, the best rotating speed of spray head is 12000r/min. |
