Shock wave phenomena, propagation and reflection, are reviewed. One dimensional propagation of exploding and imploding shock waves based on similarity methods is reviewed and in addition, decay exponents of shock waves analyzed by the shock dynamics theory of Witham are discussed for comparison. The oblique reflection of shock waves on a wall is also reviewed for both steady and quasi-steady flows. Results of numerical simulation for various types of shock reflection are discussed. Recent advances on reflection phenomena are also covered.

気体と液体の二つの相の領域を考え,気体中で発生した爆風が境界面を通して液体中へ伝ぱする問題を波の干渉を考慮して解析した.解析結果はエクスプローデイング・ワイヤによる実験結果と良く一致し,特に水面上の爆発に対する結果を良く説明できた.また,水中へ透過した圧力波の伝ぱ速度は,水面上で最も強く爆風の影響を受け,ある一定時間後に水の音速まで減衰する.

This study is concerned with hemodynamics of branching flows in the cerebral circulation, which is important in pathogenesis of regional ischemic lesion or hypertensive intracerebral hemorrhage occurring preferentially in the basal ganglia. A series of measurements of energy-loss coefficients at branching sites under laminar steady flow have been conducted in model branches having various geometries. Furthermore, the effect of branching on blood supply to its distal area is described using a lumped-parameter model which was constructed according to the measurement of the vascular architecture in the basal ganglia.It is emphasized that, in circulation in vivo, the branching loss is important where a small artery divides off from a large trunk. It is also indicated that the effect of such branchings may become more significant when the autoreguratory mechanism is abolished under pathological conditions such as CO-poisoning. (J. Jpn. Soc. Biorheol., 1 (2), 77~85, 1987).
