Experimental investigation of a cavitating Venturi and its application to flow metering [PDF]

open access: yes, 2021
An experimental investigation has been carried out to evaluate the performance of a cavitating Venturi flow. For that purpose, a closed loop circuit with a centrifugal pump and a transparent asymmetric converging-diverging test section has been built ...

The Polytropic Approach in Modeling Compressible Flows Through Constant Cross-Section Pipes [PDF]

open access: yes, 2021
A compressible flow with wall friction has been predicted in a constant cross section duct by means of a barotropic modeling approach, and new analytical formulas have been proposed that also allow any possible heat transfer to the walls to be taken into

Accidental releases of two-phase multicomponent critical flow from horizontal pipes [PDF]

open access: yes, 2000
An accident involving a two-phase release can result in serious consequences for people as well as the environment. Consequently, tools are needed to give accurate predictions of the discharge rate, physical state, composition of released material, and ...

NUMERICAL INVESTIGATION OF CHOCKED CONVERGING-DIVERGING NOZZLES FOR THRUSTER APPLICATION [PDF]

open access: yes, 2011
The need for low-thrust propulsion systems for small scale spacecraft is growing. Low thrust characteristics generally lead to low Reynolds number flows from propulsive devices that utilize converging-diverging nozzle.

Impact of vacuum degree on the aerodynamics of a high-speed train capsule running in a tube [PDF]

open access: yes, 2021
Motivated by the growing scientific and engineering interest in evacuated tube railway transportation systems, in this paper we numerically study the influence of the vacuum degree on the flow field around a train capsule running in an evacuated tube ...

Numerical simulation of the fluid flow though valves based on Large Eddy Simulation models [PDF]

open access: yes, 2009
The aim of this paper is to carry out a group of numerical experiments over the fluid flow through the valve reed, using the CFD&HT code TermoFluids, a new unstructured and parallel object-oriented CFD code for accurate and reliable solving of industrial

Inflation Control in a CVAR Model With an Application to the Burns/Miller Period in the USA

open access: yesOxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 803-813, August 2026.
ABSTRACT The paper addresses the problem of “how to make a nonstationary inflation rate stationary by controlling the policy instrument”. It shows that a necessary condition is a significant non‐zero element in the long‐run impact matrix. An application to US data covering the Burns/Miller periods finds a significant, but positive, long‐run impact on ...

Compressibility and rarefaction effect on pressure drop in rough microchannels [PDF]

open access: yes, 2007
A numerical analysis of the flow field in rough microchannel is carried out with a finite volume compressible solver, including generalized Maxwell slip flow boundary conditions suitable for arbitrary geometries. Roughness geometry is modeled as a series
