| Abstract: | Mathematical models have been successfully developed to numerically simulate leakage of the multi-level series seal.In the leakage simulation of 3-level series seal,the relationship between the leakage rate,leak quantity,and time was evaluated.In this case,the simulated and the experimental results agree fairly well,showing the simulation works.The rules derived from the simulation may work well in design of multi-level series seal,leak detection and safety evaluation of high pressure tanks. |
