| Abstract: | Several calculational methods of labyrinth seals presented in the past were analyzed on different aspects,such as theoretical considerations,characters of the formula,application limits and so on.A simple analytical and explicit numerical iteration method was presented.The results obtained with this method were compared with the ones obtained by both numerical and experimental techniques.After verifying by some examples,the method is found effectively to both subcritical and critical problem,and it can accurately predicts leakage rates of straight seal,stepped seal,staggered seal and other types of labyrinth seals. |
