Forecast Study on the Overall Coefficient for Passage of Single-Phase and Passage of Single-Phase in an Annular to Plain Tubes Heat Stream

چکیده
Abstract To prevent buoyancy effects from increasing the overall heat transfer coefficient due to low flux, smooth vertical circular tubes require forced convection conjectures. Previous research has focused on mixed in turbulent regions and limited studies convective transfer. This study aims investigate predictable coefficients of performance under specific conditions convection, considering both up flow down through test section. The recommended Reynolds numbers for water are (7201.6–14577.4) (3186.7–6396.75) single-phase annular passages, respectively, with a application range (50–500 W). is (333.91 - 432.95 W/m2.K) (169.76 251.20 respectively. was all fluxes.

Implementation of Single-Qutrit Quantum Gates via Tripod Adiabatic Passage
We proposed and analyzed implementation of the single-qutrit quantum gates based on stimulated Raman adiabatic passage (STIRAP) between magnetic sublevels in atoms coupled by pulsed laser fields. This technique requires only the control of the relative phase of the driving fields but do not involve any dynamical or geometrical phases, which make it independent of the other interaction details: ...

the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
