Rarefied Gas Dynamics is a field of science primarily concerned with the study of gas flows in which processes on a molecular level are relevant. With diverse applications spanning from astrophysics to micro-flows, it continues to raise challenging questions that require a multi-disciplinary effort by mathematicians, physicists, chemists, computational scientists and engineers.
