Subcriticality [PDF]

open access: yes, 2021
AbstractFor a subcritical reactor system driven by a periodically pulsed spallation neutron source in KUCA, the Feynman-α and the Rossi-α neutron correlation analyses are conducted to determine the prompt neutron decay constant and quantitatively to confirm a non-Poisson character of the neutron source.

Small Thermal Fluctuation on a Large Domain [PDF]

open access: yes, 1996
Weak first-order phase transitions proceed with percolation of new phase. The kinematics of this process is clarified from the point of view of subcritical bubbles.

Subcritical dual models as subcritical strings

open access: yesPhysics Letters B, 1990
Abstract We reconsider the nonplanar loop of the bosonic dual resonance model with space-time dimension D in the range 1 D ϱ(μ)=2| sinh πμ[ (25−D) 48 + i (D−1) 48 ]| 2 . We point out many parallels of this result with the picture of subcritical strings advanced by Polyakov.

Nonexistence of Subcritical Solitary Waves [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2021
AbstractWe prove the nonexistence of two-dimensional solitary gravity water waves with subcritical wave speeds and an arbitrary distribution of vorticity. This is a longstanding open problem, and even in the irrotational case there are only partial results relying on sign conditions or smallness assumptions.

Exergy Analysis and Performance Improvement of a Subcritical/Supercritical Organic Rankine Cycle (ORC) for Exhaust Gas Waste Heat Recovery in a Biogas Fuelled Combined Heat and Power (CHP) Engine Through the Use of Regeneration

open access: yesEnergies, 2019
In the present study, a subcritical and supercritical regenerative organic Rankine cycle (rORC) was designed. The designed rORCs assist a combined heat and power (CHP) engine, the fuel of which is biogas produced from anaerobic digestion of domestic ...

Multi-Objective Thermo-Economic Optimization Strategy for ORCs Applied to Subcritical and Transcritical Cycles for Waste Heat Recovery

open access: yesEnergies, 2015
Organic Rankine cycles (ORCs) are an established technology to convert waste heat to electricity. Although several commercial implementations exist, there is still considerable potential for thermo-economic optimization.
