Simulation of Supercritical CO2 Flow Through Circular and ...

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.

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 ...

Supercritical Flow Synthesis of Pt1–xRux Nanoparticles ...

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 ...

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.
