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

open access: yesJournal 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

open access: yesJournal 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 ...

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)

open access: yesInternational 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.

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

open access: yesArchives 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.

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

open access: yesBrain, 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

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

open access: yesTRANSACTIONS 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.

CONSTRUCTAL DESIGN OF A VORTEX TUBE FOR SEVERAL INLET STAGNATION PRESSURES

open access: yesRevista de Engenharia Térmica, 2012
The present paper shows a numerical study concerned with the geometrical optimization of a vortex tube device by means of Constructal Design for several inlet stagnation pressures. In the present study, it is evaluated a vortex tube with two-dimensional axisymmetric computational domain with dry air as the working fluid.
