The paper presents three one - dimensional models to simulate gaseous flows in micro - channels. These include no - slip flow, simple fully - developed, and locally fully - developed models. It is shown that the locally fully - developed model provides a more accurate prediction when both rarefaction and gas acceleration need to be considered in micro - flows. Furthermore, the effects of rarefaction and gas acceleration on the locally dimensionless pressure ratio are specified on the basis of the three models. The validation of these models is accomplished by comparison with the experimental results.
