Abstract
The paper deals with a non-isothermal case T*<1 of an airflow around circular cylinder in cross flow at the regime of laminar vortex shedding. Lecordier et al.(1991) originally proposed the effective Reynolds number and effective temperature concept. Wang et al. (2000) derived Teff from experiments proposed c=0.28 and St-Reeff curve for T* between 1 to 2. The thesis confirm that Wang et al.(2000) effective temperature and St-Reeff curve for T*<1.
This thermal effect is consistent with known effect of flow stabilization by cylinder heating.
