Analytical Study of the Bed Roughness and Entrainment Ratio of Saline Density Currents on Hydraulic Jump [PDF]

مهندسی منابع آب, 2017
Density current is produced due to a density contrast with the ambient fluid. This density difference can result from dissolved solids, suspended materials, temperature, etc.

Encapsulated Leptin-Producing Cells Facilitate Entrainment of Circadian Rhythms in Rodents and Nonhuman Primates. [PDF]

Adv Sci (Weinh)
A clinically translatable cell line can be engineered to produce leptin, encapsulated in biomaterial and safely implanted to produce and deliver the metabolic regulating protein within the body. Implantation of these encapsulated cells decreases the time it takes for mice and non‐human primates to adjust to circadian disruptions similar to those ...

Entrainment ratio analysis of compress/ejector refrigeration system [PDF]

Proceedings of the 2015 International Conference on Advances in Mechanical Engineering and Industrial Informatics, 2015
Entrainment ratio is one of the main characteristic parameters of ejector. Studding on it is of a quiet importance to the compression/ejector refrigeration system. Computational Fluid Dynamics (CFD) is used to simulate the inner flow and analyse the influence of driving fluid pressure and outlet pressure to the performance of ejector. By simulating the

Experimental and numerical investigation of two phase ejector performance with the water injected into the induced flow

International Journal of Advanced Nuclear Reactor Design and Technology, 2020
When injectors are used in petroleum industries or sea water desalination system, it is a special case that the induced gas is accompanied by water, the ejector is in two-phase operation. In the present study, the ejector performance at two phase flow is

MEASUREMENT OF ENTRAINMENT RATIO DURING HIGH FREQUENCY JET VENTILATION

British Journal of Anaesthesia, 1990
We have measured tidal (VT), entrained (Ve) and "blowback" (Vbb) volumes during high frequency jet ventilation (HFJV) through a Mallinckrodt Hi-Lo Jet tracheal tube in anaesthetized patients. The above volumes were calculated by digital integration of the appropriate regions of flow curves derived from a pneumotachograph placed between the bias flow ...

The Relationship between Flux Coefficient and Entrainment Ratio in Density Currents [PDF]

Journal of Physical Oceanography, 2010
Abstract The authors explore the theoretical and empirical relationship between the nonlocal quantities of the entrainment ratio E, the appropriately depth- and time-averaged flux coefficient Γ, and the bulk Froude number Fro in density currents.
