Chinese Journal of Mechanical Engineering

Table 3 Variation of the vortex size as function of the slots inclination angle for Re = 4 × 10⁴

Vessel	Unbaffled vessel	Baffled vessel	Vessel with slots of F/D = 1/5
Inclination angle	–	–	α = 0°	α = 10°	α = 22.5°	α = 32.5°
Direction + ω	0.667	0.434	0.468	0.479	0.538	0.570
Direction − ω	0.667	0.434	0.468	0.440	0.427	0.391
