Hydrodynamic Evaluation of Shunt Performance in Hydrocephalus

Developmental Medicine & Child Neurology, 1968
SUMMARYA method is described for the measurement of function of ventriculoatrial and ventriculo‐peritoneal shunts in situ. The method is based on the recording of the steady state response of the intraventricular fluid pressure to slow continuous fluid infusion into the ventricular system.

Hydrodynamics and performance in fluidized bed adsorption

Biotechnology and Bioengineering, 1995
AbstractThe performance of fluidized bed adsorption is strongly influenced by the hydrodynamics of the fluidization process. Especially axial mixing in the liquid and solid phase may lead to reduced capacity and resolution. In this article axial mixing in the liquid phase of a classified fluidized bed based on porous glass granules is presented.

A Performance Model of the Krak Hydrodynamics Application

2006 International Conference on Parallel Processing (ICPP'06), 2006
We present an analytic performance model of a large-scale hydrodynamics code developed at Los Alamos National Laboratory. This modeling work is part of an ongoing effort to develop models and modeling techniques for large-scale codes and systems of interest to Los Alamos and the national laboratory community (Kerbyson et al., 2001).

Hydrodynamic performance of additively manufactured minichannels

2021 20th IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (iTherm), 2021
Additive manufacturing can be used to fabricate components with complex flow channels for a variety of applications. Examples includes minichannels through with fluids flows for heat transfer applications. However, an efficient design of such systems requires a deep understanding of the thermal and hydrodynamic performance on channel surfaces.

Foilborne hydrodynamic performance of Jetfoil

Journal of Hydronautics, 1980
The Boeing Jetfoil Model 929-115 hydrofoil ship was derived from Model 929-100, with increased forward foil area larger load-carrying capacity. Forward and aft foil contours were revised to increase cavitation margin. New hydrodynamic design methods were employed to maximize foil thickness for minimum structural weight.

Hydrodynamic Performance of Gas Microbearings

Journal of Tribology, 2004
Hydrodynamic performance of gas microbearings, fabricated with deep X-ray lithography and electroplating, will be presented in this article. Static performance in terms of load parameters and attitude angles was calculated using Molecular Gas Lubrication (MGL) theory.

Numerical Simulation of the Hydrodynamic Ship Performance

2018
The study provides a numerical investigation of the ship hull performance for the Japan Bulk Carrier (JBC hereafter). The study includes computations for the ship resistance, trim and sinkage, free-surface elevation and wake flow for both, the bare hull and for the ship equipped with an energy saving device.

Hydrodynamic Performance of Pipe Underdrains

Journal of the Irrigation and Drainage Division, 1978
Theoretical analysis and laboratory investigations of flexible-flap drain valve in high-velocity open channel flow are presented. Main hydrodynamic characteristics of the valve are: (1)Radial diffuser action, which prevents the valve from opening at low pressures; and (2)uplift forces, caused by high-velocity flow in the channel, helping the valve to ...

Hydrodynamic Performance of Porpoises ( Stenella attenuata )

Science, 1966
Two specimens of Stenella attenuata , trained to chase a winch-towed lure, reached a top speed of 11.03 meters per second (21.4 knots) in 2.0 seconds. The maximum power output, occurring 1.5 seconds after the start, was calculated from measured values of acceleration and drag coefficient.
