Abstract :
The flow Characteristics in vapor seal has a significant effect on the performance of vapor seal. Considering the flow field characteristics and engineering applications, the following work has been done: First, based on the theoretical analysis, the factors which have effect on sealing is found out. Second, models of the labyrinth glands with straight teeth have been established using CFD method. The full-flow simulation results are acquired. At last, the characteristics of the flow field in labyrinth glands with straight tooth have been analyzed according discharge coefficient.
