Role of Froude supercritical flow in active margin basin-floor fans, The
… fan and tests the hypothesis that whether Froude supercritical flow and a high degree of channelization are common features in basin floor fans, even in a distal part. The Froude supercritical flow may control the architecture and characteristics of basin-floor fan. To test this hypothesis, two …

Spatially varied flow with decreasing discharge
… the hydraulic behavior of spatially varied flow with decreasing discharge and to check the suitability of theoretical dynamic equations of water surface profile developed from both momentum principle and energy principle. Method of analyses used in this paper included: (1) experimental study …

Experimental and Numerical Investigations of Optimized High-Turning Supercritical Compressor Blades
Cascade testing and flow analysis of three high-turning supercritical compressor blades were conducted. The blades were designed at an inlet Mach number (M1) of 0.87 and inlet flow angle of 48.4 deg, with high camber angles of about 55 deg. The baseline blade was a conventional Controlled Diffusion …

Gap winds in a fjord : Howe Sound, British Columbia
Gap, outflow, or Squamish wind, is the cold low level seaward flow of air through fjords which dissect the coastal mountain barrier of northwestern North America. These flows, occurring mainly during winter, can be strong, threatening safety, economic activity and comfort. Howe Sound gap winds were …

Slug Formation and Frequency of Slugging in Gas-Liquid Flows
… When the Froude number of the stratified flow in a horizontal pipe at the onset of slug flow is less than unity, the frequency is related to the motion of upstream propagating gravity waves associated with the formation of slugs. A stochastic model is used to describe the frequency for …

Spatial and temporal variability of tide-induced salt flux in a partially mixed estuary
… of tidal salt flux scales with the river flow and has no clear dependence on the spring-neap tidal forcing. The diffusive fraction, ν, has a value of -0.25 to 0.46 in the lower estuary, increasing to -0.23 to 1 near the head of salt. The phase lag between tidal salinity and velocity is …

Implications of Shallow Water in Numerical Simulations of a Surface Effect Ship
… numbers resulting in subcritical, critical, and supercritical flow regimes. Resistance, pitch response, and free surface response of the SES were compared between the shallow water simulations. The SES produced wider wakes, perpendicular to the craft, at simulations closer to the critical flow …

A Simple Numerical Model for the Study of Baroclinic Estuarine Shelf Interactions
… open. The channel was forced with a constant inflow velocity spun up from 2 cm s<sup>-1</sup> to 27 cm s<sup>-1</sup>over five days. The model initial conditions were a flat interface at ten meters and zero velocity except at the inflow. Effects of varying interfacial friction, Newtonian cooling …

Demagnetisation of solid 3He and supercritical superflow
… well-known Landau velocity. In superfluid 3He, flow around an oscillating body displays a very clear onset of such dissipation. However, with this experiment it was found that for a uniform linear motion there is no discontinuity whatsoever in the dissipation as the Landau critical velocity is …
