Hydrodynamic performance of additively manufactured minichannels
2021 20th IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (iTherm), 2021Additive 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, 1980The 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 Evaluation of Shunt Performance in Hydrocephalus
Developmental Medicine & Child Neurology, 1968SUMMARYA 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, 1995AbstractThe 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.

Hydrodynamic Performance of Pipe Underdrains
Journal of the Irrigation and Drainage Division, 1978Theoretical 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, 1966Two 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.
