Critical Drag Investigation for an Axisymmetric Projectile with Choked Base Bleed at High-Subsonic and Transonic Regime Using SST K-? Model
In the following paper, the effects of a choked jet exhausted from the base of a non-lifting body on its total and base drags at sub-sonic and transonic regimes has been numerically investigated. Having surveyed the results of some turbulence models and after comparing with experimental results, an appropriate turbulence model i.e. SST K-?, has been chosen and this model has been used in the su...

This is an experimental comparison Of two axi-symmetric, isentropic plug nozzles. In one of these (Model No. 1) the afterbody is cylindricaland a secondary flow is bled into the annular base. The other (Model No. 2) has a parabolic afterbody with no base or bleed. In both cases the expansion is all-external and the design pressure ratio is 14. These models were tested over a range of primary an...
متن کاملNuclear medicine gastrointestinal bleeding examination utilizing an UltraTag kit reveals unusual bone marrow and hepatic uptake: a case study report.
In vitro gastrointestinal (GI) bleed testing such as the UltraTag kits has been successfully used for a number of years. None of the research studies identified reported any significant bone marrow and liver uptake. An 80-y-old male patient was admitted to the hospital for rectal bleeding. An initial GI bleed study using the UltraTag kit was normal. Two days later, a second GI bleed scan was pe...
متن کاملSilicone Gel Bleed on Breast Implants
Silicone is a polymer widely used for medical purposes, including breast implants. The aim of this work is to verify the occurrence of silicone gel diffusion through the lining membrane (bleed) of gel breast implants with smooth, textured, and polyurethane foam coated surfaces, sterilized by dry heat and ethylene oxide. The results enable us to conclude that there is significant difference for ...
متن کاملExperimental application of extremum seeking on an axial-flow compressor
We show an application of the method of extremum seeking to the problem of maximizing the pressure rise in an axial flow compressor. First we apply extremum seeking to the Moore–Greitzer model and design a feedback scheme actuated through a bleed valve which simultaneously stabilizes rotating stall and surge and steers the system towards the equilibrium with maximal pressure. Then we implement ...
