Investigation on Gas Hydrate Slurry Pressure Drop Properties in a Spiral Flow Loop

open access: yesEnergies, 2018
Although many studies have been conducted to investigate the hydrates formation and slurry flow during the transportation, studies on the hydrates slurry pressure drop properties using spiral flow in a loop are still almost blank.

Thermal-hydraulic simulation and evaluation of a natural circulation thermosyphon loop for a reactor cavity cooling system of a high-temperature reactor

open access: yesNuclear Engineering and Technology, 2020
The investigation into a full-scale 27 m high, by 6 m wide, thermosyphon loop. The simulation model is based on a one-dimensional axially-symmetrical control volume approach, where the loop is divided into a series of discreet control volumes.

Controlling heat ratchet and flow reversal with simple networks

open access: yesPhysical Review Research, 2023
We investigate ratcheting heat flow in simple networks consisting of a one-dimensional nonlinear chain with a self-coupled loop when the average thermal bias is zero.

Investigations in an external-loop airlift photobioreactor with annular light chambers and swirling flow [PDF]

open access: yes, 2011
Photosynthetic microorganisms could serve as valuable compounds, but also for environmental applications. Their production under controlled conditions implies to design specific reactors, named photobioreactors, in which light supply is the main ...

Thermal Impact by Open-Loop Geothermal Heat Pump Systems in Two Different Local Underground Conditions on the Alluvial Fan of the Nagara River, Gifu City, Central Japan

open access: yesEnergies, 2022
An alluvial fan is a good area to install open-loop geothermal heat pump (GHP) systems due to shallower aquifers, faster groundwater flow, and fewer land subsidence risks.

Post-Operative Flow-Volume Loops [PDF]

open access: yesAnaesthesia and Intensive Care, 1977
A study of flow-volume curves pre- and post-operatively demonstrated a marked difference between bronchitic and non-bronchitic patients. All bronchitic patients showed lower flow rates at low lung volumes post-operatively, when compared with their pre-operative values. Non-bronchitic patients all had higher flow rates for the same comparison.

Loops in multicommodity flows [PDF]

open access: yes1977 IEEE Conference on Decision and Control including the 16th Symposium on Adaptive Processes and A Special Symposium on Fuzzy Set Theory and Applications, 1977
Given the traffic flow from each source to each destination in a network and given the aggregate traffic in each link, we want to find if there is any looping of traffic. A careful definition of looping shows that the question is equivalent to whether some of the aggregate link flows can be reduced without increasing any of the others. It is then shown,

Plasma Flows in the Cool Loop Systems [PDF]

open access: yesThe Astrophysical Journal, 2019
Abstract We study the dynamics of low-lying cool loop systems for three data sets as observed by the Interface Region Imaging Spectrograph. Radiances, Doppler shifts, and line widths are investigated in and around observed cool loop systems using various spectral lines formed between the photosphere and transition region (TR). Footpoints
