Experimental parametric studies on the performance and mixing characteristics of a low area ratio rectangular supersonic gaseous ejector by varying the secondary flow rate

Energy, 2018
A low area ratio rectangular supersonic gaseous ejector is subjected to parametric evaluation to calculate the performance parameters like stagnation pressure ratio, compression ratio, entrainment ratio and the mixing parameter known as non-mixed length ...

Secondary Flow in Axial-Flow Turbomachinery

Journal of Fluids Engineering, 1955
Abstract A method is presented by which one can include the principal effects of secondary flow in the design of multi-stage axial-flow turbomachinery. The method uses the conventional axial-symmetry solution as a basic flow picture from which the induced turning and radial velocities characteristic to the secondary flow can be deduced ...

Secondary Flow and Atherogenesis

1988
Hemodynamic factors appear to affect atherosclerosis. Secondary flow in the aorta was studied by subjecting rabbits to constant pressure perfusion fixation and observing endothelial arrangement by scanning electron microscopy.

Secondary instability in rotating-disk flow

Journal of Fluid Mechanics, 1990
Primary instability of the three-dimensional boundary layer on a rotating disk introduces periodic modulation of the mean flow in the form of stationary crossflow vortices. Here we study the stability of this modulated mean flow with respect to secondary disturbances.

Flow electrification induced electrohydrodynamic secondary flow

1999 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat. No.99CH36319), 2003
Theoretical and numerical investigations have been conducted to evaluate the on-set conditions of flow electrification induced electrohydrodynamic secondary flow in smooth pipe and pipe with multiple cylinders in cross flow conditions. The nondimensional parameters control flow electrification and electrohydrodynamic (EHD) flow were derived from the ...

Adaptation of secondary flow in nearly-horizontal flow

Journal of Hydraulic Research, 1986
To implement the generation and decay of secondary flow in steady or quasi-steady nearly-horizontal flow models an approximative method is proposed which takes account of the convection of momentum...

Secondary flow due to Alfvén waves

Journal of Fluid Mechanics, 1977
Large (gigajoule) amounts of energy can in principle be stored as kinetic energy in liquid metal circulating round a torus and can be extracted at the gigawatt level by Alfvén waves propagating along an imposed axial field. A major limitation on the energy that may be so stored is the disruption of these primary Alfvén waves by secondary flows in ...
