Slow Reactivity Insertion in Subcritical Reactors. Application to ADS [PDF]
, 2008 As there is a need to deal with the problem of radioactive waste of nuclear plants, prototypes of subcritical reactors are being developed at the moment. They are known as ADS and they have as their main goal, the actinides transmutation.

Hydrodynamic Characteristic and Prediction Study of 1, 1, 1, 2-Tetrafluoroethane under Supercritical Pressure [PDF]
Journal of Applied Fluid MechanicsThe supercritical organic Rankine cycle (S-ORC) is highly effective for utilizing medium- and low-temperature heat sources. This study investigated the hydrodynamic behavior of supercritical-pressure 1,1,1,2-tetrafluoroethane (R134a) within a horizontal ...

Deformation, Creep, and Dynamics in Glassy Ionomers
Journal of Polymer Science, EarlyView.Ionic architecture tunes the inelastic deformation of glassy ionomers. Simulations show that ionic associations leave the small‐strain elastic baseline nearly unchanged, but strongly reinforce yielding, strain hardening, and creep resistance. Polyampholyte architectures suppress nonaffine mobility and stress‐induced fluidization most effectively by ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The progressive weakening of alpine rockwalls through subcritical cracking, driven by repeated low‐magnitude stress processes, plays a key role in alpine rock weathering. Laboratory studies using acoustic emission (AE) monitoring have shown that thermal stresses from freeze–thaw cycling induce crack propagation, with recent work highlighting ...

Air-Flow over Hills of Moderate Slope
, 1982 A three‐layer model is presented. This describes the flow on an inversion capped boundary layer over hills of moderate size and slope. The linearized vorticity equation is solved using non‐linear boundary conditions.

Natural convection of viscoplastic fluids in a triangular enclosure
Applications in Engineering ScienceThis study extends the analysis of natural convection in a viscoplastic fluid to flow within a triangular enclosure. The finite-element approach provided a numerical solution to the continuity, momentum, and energy equations. The governing parameters for

Observations and numerical simulations of a valley‐exit wind in the Alpine Bolzano basin
Quarterly Journal of the Royal Meteorological Society, EarlyView.The evolution and spreading of the nocturnal valley‐exit wind flowing from the Isarco Valley into the Bolzano basin, in the Italian Alps, are found to be influenced by the basin temperature stratification. Measurements and high‐resolution simulations show that a cold‐air pool favors an upward trajectory of the flow at the exit of the valley.
