建立了计算小间隙内气体泄漏量的数学模型,模型中同时考虑了惯性力和粘性力的影响。泄漏量的理论值与实验值吻合良好。
A mathematical model for calculating the amount of gas leakage in a small gap was established. The influence of both inertial force and viscous force was considered in the model. The theoretical value of leakage is in good agreement with the experimental data.
