Based on the flow patterns in the vent and the corresponding modes of heat transfer through it, three flow regimes were identified: the conduction regime (Ra [less than or equal to] 1500), the countercurrent flow regime (1600 [less than or equal to] Ra < 3600), and the oscillatory flow regime (Ra [greater than or equal to] 3600).
