Colloquium: A Talk about Heat and Mass Transfer Phenomena in the Free-and Near-Free-Molecular Flow Regimes

You are cordially invited to attend the Second Aerospace Engineering Colloquium!

The Stephen B. Klein Faculty of Aerospace Engineering Colloquium series is a prime stage to spotlight the faculty researchers and the most up-to-date scientific work our faculty members conduct. On our second Colloquium, Assoc. Prof. Avshalom Manela will speak at the Aerospace Engineering Colloquium about Heat and Mass Transfer Phenomena in the Free-and Near-Free-Molecular Flow Regimes.

The analysis of non-continuum gas flows, modeled in the framework of gas kinetic theory and associated Boltzmann equation, is a challenging task that commonly requires heavy-load numerical computations. Yet, seeking more mathematical and physical insight, rigorous investigations are much desirable. To this end, the free- and near-free-molecular flow regimes, characterized by high rarefaction rates, are relatively convenient to handle. This talk will present some recent work on this topic, including problems in acoustics, microchannel mass transfer, and flow detachment. For each problem, analytical predictions will be presented, accompanied by numerical calculations for validation.
