 note = {A numerical analysis of axisymmetric gas-particle two phase flows is described. Under-expanded supersonic free-jet flows and supersonic flows around a truncated cylinder of gas-particle mixtures are solved numerically on super computer Fujitsu VP-200. Although the gas phase is treated as a continuum medium, the particle phase is done partly as a discrete one. The particle cloud is divided into a large number of small ring clouds. In each cloud, the particles are approximated to have nearly the same velocity and temperature. The particle flowfield is obtained by following these individual ring clouds separately in the whole computational domain. In estimating the time rates of momentum and heat transfers from the particle phase to the gas one, the contributions from these ring clouds are averaged over some volume whose characteristic length is sufficiently small compared with the characteristic length of the flowfield but sufficiently large compared with that of the ring clouds. The numerical results have shown that the flow characteristics of the gas-particle mixtures are very much different from those of the dust-free gas., 資料番号: NALSP0009028, レポート番号: NAL SP-9},
