Abstract : This report summarizes the work done at A.R.S. in the field of rarefied gas dynamics under contract with A.F.O.S.R. during the period from 1 August 1968 to 31 July 1969. After an introduction describing the essential mathematical tools for a theoretical investigation on the behavior of rarefied gases in the so-called transition regime, two main lives of work are reviewed in some detail, i.e. the research for new methods for finding approximate solutions of the linearized Boltzmann equation and the investigation of physically realistic boundary conditions to be matched with the Boltzmann equation.
