Control of Reynolds number in a high speed wind tunnel [PDF]

Journal of Aerospace Technology and Management, 2009
A conceptual control model for the Reynolds number test based on isentropic relations was established for the supersonic wind tunnel. Comparison of the system response of the model simulation and the actual wind tunnel test data was made to design the ...

Drag and pressure fields for the MHD flow around a circular cylinder at intermediate Reynolds numbers

Journal of Applied Mathematics, 2005
Steady incompressible flow around a circular cylinder in an external magnetic field that is aligned with fluid flow direction is studied for Re (Reynolds number) up to 40 and the interaction parameter in the range 0≤N≤15 (or 0≤M≤30), where M is the ...

Computational Analysis on the Performance of Centrifugal Compressor with Tapered Wall and Rotating Tapered Wall Vaneless Diffuser

Journal of Applied Fluid Mechanics, 2021
Computational analysis is performed on a centrifugal compressor fitted with tapered vaneless diffuser in order to increase the rate of diffusion. The main parameter involved in the present study is the wall taper angle of the diffuser, which is varied ...

On the influence of the nozzle external configuration on the radiated screech and the decay of supersonic jets

Archives of Acoustics, 2016
The behaviour of screeching jets exhausting from an axisymmetric con-vergent-divergent nozzle was studied. The nozzle had a 2.9 mm throat diameter and a. 1.95 theoretical exit Mach number.

CFD analysis of the internal hydraulic mechanism and validation of the measurement principle of a slit-type velocimeter

Discover Water
Low-cost, robust multipoint velocity monitoring is essential for advancing watershed flood-management strategies. This study aims to validate the measurement principle of a low-cost, slit-type velocimeter by examining its internal physical mechanisms ...

Normal pressure hydrocephalus (NPH): ischaemia, CSF stagnation or both [PDF]

Brain, 2004
Normal pressure hydrocephalus (NPH) is a clinical and radiographic syndrome first described by Hakim and Adams in 1965 (Hakim and Adams, 1965) and characterized clinically by gait apraxia (‘magnetic gait’), incontinence and dementia, and diagnosed predominantly among people over the age of 60 years. Only a minority of patients present with the complete

Flow Field in the Turbine Rotor Passage in an Automotive Torque Converter Based on the High Frequency Response Rotating Five-hole Probe Measurement Part I: Flow Field at the Design Condition (Speed Ratio 0.6)

International Journal of Rotating Machinery, 2001
The relative flow field in an automotive torque converter turbine was measured at three locations inside the passage (turbine 1/4 chord, mid-chord, and 4/4 chord) using a highfrequency response rotating five-hole-probe.

Dynamic Properties of the Stagnation Pressure of Water Jet in the Continous Region.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1996
It is of interest to clarify dynamic properties of water jet pressure acting on the surface of an object to be cut in order to clarify the cutting mechanism. This pressure includes a wide range of frequency components from the pulsation of a plunger pump to the impact pressure caused by the impingement of droplets.

EFFECT OF CYLINDER SHAPE ON HEAT TRANSFER AND FLUID FLOW

Al-Qadisiyah Journal for Engineering Science, 2010
Two dimensional flow over single cylinder with different shapes in the free stream are numerically investigated. Consideration is given to the effect of cylinder seven shapes with the same area, and Reynolds number (Re) on heat transfer and flow ...
