Velocity of convective currents in boilover

Chemical Engineering Science, 2006
The mathematical model proposed earlier, to simulate the thin layer boilover, has been modified to represent boilover phenomenon in general. In this modified form of the model, the convection current velocity through the fuel layer is considered as a time varying parameter.

Current assessment of pulse wave velocity

Journal of Hypertension, 2019
Carotid-femoral pulse wave velocity (PWV) is considered the gold standard for arterial stiffness assessment in clinical practice. A large number of devices to measure PWV have been developed and validated. We reviewed different validation studies of PWV estimation techniques and assessed their conformity to the Artery Society Guidelines and the ...

Initial velocity currents in thermionic valves

Proceedings of the Physical Society, 1941
The electrons emitted from a thermionic cathode possess enough energy to enable them to reach other electrodes in the system providing the opposing potential is not too great. The current flowing across to any electrode when there is no actual applied potential on the electrode is referred to as the initial velocity current from the cathode to that ...

Velocities in combined undertow and longshore currents

Coastal Engineering, 1989
Abstract The flow composed of a periodic wave motion with turbulent fluctuations caused by breaking and a (slowly varying) mean current is considered. The mean current consists of the combined cross-shore and longshore current velocities generated by the waves which means the profile of the total velocity is highly three dimensional.

Velocity saturation current-mode CMOS imaging sensor

2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013
A current-mode CMOS imaging sensor is presented in this paper. The read-out transistor in the photo pixel operates in velocity saturation regime and allows for high linearity between integrated photo charges and output drain current. The column parallel read-out circuitry implements a novel current conveyor with a feedback mechanism which improves ...

Velocity Profiles in Nearshore Circulation Current

Coastal Engineering in Japan, 1985
ABSTRACTNearshore circulation current system on a plane beach produced by a uniform wave train, normally incident on the beach, is investigated experimentally. To measure mean rip and shoreward currents, a two-component electromagnetic flowmeter has been used on the beach.

Annual Velocity Variations in the Labrador Current

Journal of Physical Oceanography, 1993
Abstract Analyses of CTD and current meter data obtained between 1978 and 1988 off southern Labrador reveal two distinct regimes in the Labrador Current. The first lies over the shelf and upper slope and is the traditional Labrador Current transporting cold low-salinity water south from Baffin Bay and Hudson Strait.

Empirical equation for longshore current velocity

Journal of Geophysical Research, 1968
Ninety-eight observations of longshore current velocity, beach slope, and the breaker height, period, angle, crest length, and trough depth were made on an Atlantic ocean beach. Precision inshore surveys during the observation period revealed an essentially plane beach with an offshore bar parallel to the shoreline during two-thirds of the study period.

Dynamically constrained projection for subsurface current velocity

Journal of Geophysical Research: Oceans, 2002
An approach is described that projects surface current observations downward to obtain subsurface current structure consistent with the interior current dynamics. The projection approach is unrestricted by water depth. However, this study emphasizes well‐mixed constant density flow in water depths appropriate for mid and outer shelf, where viscous and ...

High-velocity turbidity currents, a discussion

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1954
The possibility of the transport of coarse material by turbidity currents is discussed. The difficulties in regarding such currents as responsible for the cable breaks following the 1929 Grand Banks earthquake are pointed out.
