Abstract : This report summarizes the work done in the field of rarefied gas dynamics under contract with A.F.O.S.R.. The report essentially consists of a list of the research papers prepared for publication from 1 May 1965 to 31 July 1968; for each paper the full title and an abstract is given, together with the proper reference. This list comprises 25 papers, mainly devoted to the study of specific problems of flows in the transitions regime, i.e., in that regime of rarefaction where the mean free path is of the same order of magnitude as a characteristic length. The main original contributions range from the suggestion of new methods of solution for the Boltzmann equation to the detailed treatment of specific problems of particular interest, such as the Poiseuille and Couette flows in different geometries, flow past an axisymmetric obstacle, influence of the wall accomodation properties on the results of the above problems.
