Development of a Hydraulic Conical Valve for the Linearization of Flow

open access: yesMachines
Conventional throttling valves have non-linear flow characteristics. However, in precise processes of flow control requiring them, appropriate flow modulations are necessary to enable a linear flow response even under partial valve actuations. This paper

3D unsteady flow in oscillating compressor cascade [PDF]

open access: yes, 2004
An experimental and computational study has been carried out to enhance current understanding of three dimensional (3D) cascade aeroelastic mechanisms. 3D unsteady pressure data produced during executing this project is the first-of-its-kind, which can ...

An overview of collective effects in circular and linear accelerators [PDF]

open access: yes, 1989
The purpose of both linear and circular accelerator is, of course, to accelerate beams of charged particles. In order to do this it is necessary not only to accelerate particles but also to confine them transversely so that they remain in the vacuum ...

High Accuracy Volume Flow Rate Measurement Using Vortex Counting [PDF]

open access: yes, 2013
A prototype device for measuring the volumetric flow-rate by counting vortices has been designed and realized. It consists of a square-section pipe in which are placed a two-dimensional bluff body and a strain gauge force sensor.

Optimal linear power flow for droop controlled islanded microgrid

open access: yesInternational Journal of Electrical Power & Energy Systems
The time of optimal planning and operation of islanded microgrid (IMG) can be minimized by modeling it as non-iterative mixed integer linear problem (MILP).

Modified Ricci flow on a principal bundle [PDF]

open access: yes, 2008
textLet M be a Riemannian manifold with metric g, and let P be a principal G-bundle over M having connection one-form a. One can define a modified version of the Ricci flow on P by fixing the size of the fiber.

Non Linear Modelling and Control of Unified Power Flow Controller [PDF]

open access: yesE3S Web of Conferences
Unified Power Flow Controller is modeled as a non linear system in order to apply a non linear control technique for the improvement of power flow in a Single Machine Infinite Bus system.
