Numerically predicted time variation of the fraction of levitating cells in the flow chamber for cases 0 V (no AC voltage applied) and 20 V (Vpp = 20.0 V) with a frequency of 10 kHz. The mean velocity of the cell suspension was um = 0.28 mm/s. The ratio of live and dead cells was 1:1 with a cell volume fraction of ϕ = 3 × 10−3.
