“…The flow structure observed in Fig. 7c for the dimensionless frequency (equal to x ¼ 35À88 in this study) is qualitatively consistent with the findings of a previous study [25].…”

“…Periodic changes in the flow rate of the fluid pumped through the channel result in the generation of average flows in each of the channel cells. The earlier experimental study of averaged flows excited by fluid oscillations in an axisymmetric channel whose cross section varies periodically with the longitudinal coordinate [25] has shown that the parameter determining the structure and intensity of the averaged flows is a dimensionless frequency x. The dimensionless frequency…”

“…Важным результатом проведенных ранее исследований является то, что в областях умеренных и низких частот обнаружена генерация осредненных потоков, интенсивность которых уменьшается с понижением безразмерной частоты вибраций ω = ΩR 2 /ν. В работе [7] показано, что гармонические колебания жидкости в канале переменного сечения возбуждают осредненный поток в виде системы тороидальных вихревых течений, структура и интенсивность которых определяются ω и пульсационным числом Рейнольдса Re. В настоящем работе представлены результаты экспериментального исследования осцилляционной динамики твердого сферического тела в вертикальном осесимметричном канале переменного сечения при колебаниях расхода жидкости.…”

“…the drift takes place along the axis of fluid oscillations. We consider a micro-device similar to Matthias and Müller (2003) and Vlasova et al (2020) where two basins are connected via modulated channels filled with a liquid. A periodic pumping confers a back and forth fluid motion dragging the particles in suspension.…”
