Abstract: Modern gas flows, such as those exhibited by nano scale systems, are typically rarefied and oscillatory (time-varying), with frequencies ranging from O(MHz) to O(THz). The physical mechanisms which drive the flows in the low and high frequency limits are unique. While analytical slip models have been derived to model the low frequency or near-continuum regime, solutions in the high frequency limit often assume free molecular flow. In this talk, I'll discuss some key findings in the analysis of the high frequency flow regime, assuming the gas to be rarefied.
