Влияние межатомного диполь-дипольного взаимодействия на динамику спонтанного распада возбужденного состояния атома

The object of the study is an ensemble of cold atoms under conditions of strong dipole-dipole interaction. The purpose of the work is to review the literature on collective effects in non–degenerate cold atomic gases and ensembles of impurity atoms in a solid-state dielectric, calculate the quantum mechanical amplitudes of once excited states of ...

Численное исследование перемешивающей вентиляции в тестовом помещении при периодически меняющемся Ñ€Ð°ÑÑ Ð¾Ð´Ðµ приточного Ð²Ð¾Ð·Ð´ÑƒÑ Ð°

The paper presents the results of numerical modelling of air flow in a test ventilated room with ceiling supply under periodic flow rate variation. The problem was solved in 2D formulation based on the RANS/URANS approach using k-ε RNG turbulence model.
