Unsteady phenomena were observed in the case of airflows approaching transition inside a uniformly heated vertical tube. An analysis of the experimental data at three Reynolds numbers (Re = 1000, 1300 and 1600) allowed to establish that: (i) A flow instability onsets at different Grashof numbers (Gr
