| ABSTRACT |
|
Installing the air curtain for painting drying workshop is an effective method for continuous vehicle in and out. A top injection air curtain is designed for the high temperature vehicle painting drying workshop in this research. Based on the numerical simulation method, the effect of key operating parameters and working state of the air curtain on the stability and thermal dissipation performance of air curtain have been investigated. The results showed that increasing both the air curtain injection velocity and injection angle improved the stability of the top injection air curtain. Both the optimized air curtain injection velocity and the air curtain injection angle are obtained to achieve the lowest thermal dissipation effect at the fixed workshop height. The stability of the air curtain declines sharply and the thermal energy dissipation of the workshop increased obviously at high workshop height. With the vehicle skeleton passes through the air curtain, the stable gas barrier is destroyed, and the thermal dissipation is increased compared without vehicle passing. The low air curtain jet velocity is recommended with vehicle through the air curtain. Moreover, the small distance between the car bottom to the ground, and the quickly vehicles passing air curtain are suggested in actual operation.
