WebAug 14, 2013 · While the flow patterns for gravity currents on θ = 6 ∘, 9 ∘ are qualitatively different from those on θ = 0 ∘, similarities are observed in the acceleration phase for the flow patterns between θ = 2 ∘ and θ = 6 ∘, 9 ∘ and in the deceleration phase, the patterns for gravity currents on θ 2 ∘ are found similar to those on θ = 0 ∘.
