TLDR
In this paper, the results of experimental and numerical investigations of laminar flow in a pipe with a sudden contraction in its cross sectional area were summarized in order to gain an insight into the flow structure near the sudden contraction and an understanding of increased pressure losses generated in this region.About:

Comparison of finite-volume numerical methods with staggered and colocated grids
TL;DR: In this paper, a detailed comparison of two finite-volume solution methods for two-dimensional incompressible fluid flows, one with staggered and the other with colocated numerical grids, is presented.

Use of a pressure-weighted interpolation method for the solution of the incompressible navier-stokes equations on a nonstaggered grid system
Timothy F. Miller,F. W. Schmidt +1 more
TL;DR: In this paper, a detailed study of the pressure-weighted interpolation method (PWIM) using a non-staggered grid proposed by Rhie and Chow [7] was conducted.
Journal ArticleDOI
Finite difference solutions of the Navier-Stokes equations on staggered and non-staggered grids
TL;DR: A non-staggered mesh scheme that also satisfies these constraints has been developed and comparisons between it and a SIMPLE scheme for natural convection in a cavity indicate that the schemes have equivalent accuracy.

A new method for noninvasive quantification of valvular regurgitation based on conservation of momentum. In vitro validation.
TL;DR: For free jets resembling many clinical lesions, regurgitant flow rate and volume can be calculated noninvasively from Doppler velocities without planimetry of jet area, and should apply regardless of associated valvular lesions.

A review of solid–fluid selection options for optical-based measurements in single-phase liquid, two-phase liquid–liquid and multiphase solid–liquid flows
TL;DR: In this article, the authors present a review of refractive index-matching systems for single-phase and multiphase liquid-liquid flows. But, their focus is on the matching of flow similarity parameters such as density and viscosity.

Experimental and Theoretical Investigation of Backward-Facing Step Flow
TL;DR: In this paper, the velocity distribution and reattachment length of a single backward-facing step mounted in a two-dimensional channel were measured using laser-Doppler measurements.
Journal ArticleDOI
Laminar flow in the entrance region of a pipe
TL;DR: In this article, the laminar flow of an incompressible fluid in the inlet of a pipe is analyzed numerically, and the numerical technique allows a closer approximation to the basic equations of fluid motion than has been possible in previous investigations.

Steady Flow Through a Channel with a Symmetrical Constriction in the Form of a Step
S. C. R. Dennis,Frank T. Smith +1 more
TL;DR: In this article, the Navier-Stokes equations for the steady, two-dimensional, laminar flow of an incompressible fluid through a channel with a symmetric constriction in the form of a semi-infinite step change in width is given.
Journal ArticleDOI
The separating flow through a severely constricted symmetric tube
TL;DR: In this article, the axisymmetric flow of an incompressible fluid through a pipe (of radius a) suffering a severe constriction is studied for large Reynolds numbers R, the features of symmetric channel flows being virtually the same.

Flow of a newtonian fluid through a sudden contraction
James S. Vrentas,J. L. Duda +1 more
TL;DR: In this paper, the full Navier-Stokes equations describing flow through a sudden contraction are solved by an explicit finite-difference method, and Streamlines, vorticity distributions, velocity profiles, excess pressure drops and entrance lengths are calculated as functions of Reynolds number and radius ratio.
