Enteral Tube Feeding Dysphagic Stroke Patients (DRAFT)

2018
This chapter discusses the results of randomized controlled trials evaluating the benefits of early feeding for patients who suffered an acute stroke. The study was divided in two different groups: the first one compared early feeding versus avoiding nutrition, and the second compared percutaneous endoscopic gastrostomy versus nasogastric tube feeding ...

Drying of Suspensions in the Draft Tube Spouted Bed

The Canadian Journal of Chemical Engineering, 2004
AbstractA draft tube spouted bed dryer with inert particles was used for drying suspensions. The effects of the operating conditions on dryer throughput and product quality were investigated. Experiments were performed in a cylindrical column 215 mm in diameter with a draft tube 70 mm in diameter and 900 mm in length.

Model and Prototype Draft Tube Pressure Pulsations

1996
All producers of Francis turbines daily meet the problem of draft tube vortex appearance and its consequences [1,2,3,4]. Limitations in turbine operation because of the vortex appearance and undesirable consequences on hydraulic system are sufficient reason for its intensive researching.

Liquid circulation in a draft-tube bubble column

Chemical Engineering Science, 1985
Abstract A study of liquid circulation in a draft-tube bubble column (250 mm diameter, 60l. capacity) using a flow-follower technique is reported. It was observed that annulus liquid circulation velocity increased to a maximum with air flowrate and a maximum in the volumetric liquid circulation rate occurred at a tube: column diameter ratio of about ...

TURBULENT FLOW SIMULATION IN KAPLAN DRAFT TUBE

2006
This work was motivated by a need for validation of commercial CFD fluid flow solver for hydraulic turbine flow simulations. For the same reason, the ERCOFTAC draft tube has been used for many years as a base for evaluating the state-of-the-art CFD (Computational Fluid Dynamic) codes in the field of hydropower generation.
