On the effective temperature and Reynolds number concept for a heated circular cylinder: commentary of the article by Baranyi et al.

The onset of oblique vortex shedding behind a heated circular cylinder in laminar wake regime

“…17 is also plotted as the solid line in this figure for a comparison. Results from the non-isothermal cases 7,12,14,19,20 have revealed that the vortex-shedding frequency decreases with increasing cylinder temperature for the PVS mode. Similar trend also can be found for the vortex shedding frequency of OVS mode, i.e., the shedding frequency decreases with increasing temperature ratio.…”
