Supercritical flow - OilfieldWiki
Supercritical flow - OilfieldWiki

A ,supercritical flow, is when the ,flow, velocity is larger than the wave velocity. The analogous condition in gas dynamics is supersonic.. Information travels at the wave velocity. This is the velocity at which waves travel outwards from a pebble thrown into a lake.

Supercritical flow involves shallow water flowing in high velocity. The shallow water depth results in higher velocity head when compared with subcritical flow. The fast flow of water causes erosion to channel linings and beddings.

Supercritical Flow in Storm Sewers – Learn Stormwater Studio

Stormwater Studio has the ability to compute ,supercritical flow, profiles with hydraulic jumps automatically. When the energy equation cannot balance, the software initially assumes critical depth and proceeds to the next upstream Line. When finished with the subcritical profile, it reverses the calculation procedure for any Lines (circular, rectangular or open channels) with critical depth ...

For a flow speed higher than the phase speed, Fr > 1, the flow is supercritical. Changes in the coastline orientation then have abrupt effects on the flow; all the adjustment must take place downstream since the gravity waves cannot propagate against the flow.

Course: Open Channel Flow: Supercritical & Non-uniform Flow

Non-uniform ,flow, calculations are needed, however, in some open channel ,flow, situations, where the ,flow, is clearly non-uniform. The concepts of ,supercritical,, subcritical and critical ,flow,, and calculations related to those three regimes of ,flow,, are needed for non-uniform open channel ,flow, analysis and calculations.

The thermodynamic stability of nanocrystals is different from that of bulk systems, and nanoscale phase diagrams are to a large degree unknown. Here we present a systematic investigation of the Pt1–xRux phase diagram through ,supercritical flow, synthesis of Pt1–xRux nanoparticles across the entire compositional range. The synthesis was done in stoichiometric steps of 0.1 using an ethanol ...

Abstract. Using both a theoretical and an experimental approach, the main flow features in junctions with thoroughly supercritical flows are considered. The junctions are characterized by rectangular channels of equal branch width and sharpedged corners. Junction angles of 22.5° and 45° are considered.

Supercritical flow calculations have been Frformed for ellipses with thickness ratio of 0.2 and 0.4 at various free-stream Mach numbers. The present results are compared with the shock-capturing method, and good agreement is obtained. 1. Introduction Within the past decade there has been strong interest in transonic flow research.

Supercritical, CO 2 (⁠ sCO 2 ⁠) is a promising working fluid for future high-efficiency power conversion cycles.In order to develop these cycles, it is necessary to understand ,supercritical, and two-phase CO 2 ,flow,. This paper presents a methodology for the computational fluid dynamic (CFD) simulation of sCO 2 flowing through a restriction under a wide range of ,flow, conditions.
