Plug Nozzles: Summary of Flow
This paper represents an overview of the activities carried out in the framework of RTO/AVT Working Group 10, Subgroup 1, dedicated to plug nozzle aerothermodynamics and performance. The subgroup worked out two main objectives: i) thorough understanding of the flow physics of plug nozzles trough literature review and recent experiments conducted in Europe and USA; ii) definition of CFD test cas...
متن کاملAssessment of cerebral blood flow by means of blood-flow-volume measurement.
of Blood-Flow-Volume Measurement To the Editor: With great interest we read in Stroke that a working group around Soustiel1 compared cerebral blood flow (CBF) as measured by xenon clearance technique with blood-flow-volume (BFV) measurements from the internal carotid artery (ICA). Soustiel et al found well-correlated data, ie, correlation coefficients 0.75, in a total of 77 measurements. As a c...
متن کاملTissue blood flow measurement by laser Doppler technique
Measurement of blood flow and the effects of different factors on tissue blood flow are important fields of research in physiology and pharmacology. So far, different methods have been innovated, using laser light is the Last one. In this article history, principles and specifications of laser technique along with its advantages and disadvantages ( in comparison with other methods) are revie...
متن کاملDistortion of Flow Measurement and Cavitation Occurs Due to Orifice Inlet Velocity Profiles
This analysis investigates the distortion of flow measurement and the increase of cavitation along orifice flowmeter. The analysis using the numerical method (CFD) validated the distortion of flow measurement through the inlet velocity profile considering the convergence and grid dependency. Realizable k-e model was selected and y+ was about 50 in this numerical analysis. This analysis also est...
متن کاملRatcheting up energy by means of measurement.
The destruction of quantum coherence can pump energy into a system. For our examples this is paradoxical because the destroyed correlations are ordinarily considered negligible. Mathematically the explanation is straightforward and physically one can identify the degrees of freedom supplying this energy. Nevertheless, the energy input can be calculated without specific reference to those degree...
