Shear induced force on a bubble in a bubble swarm
Shear induced force on a bubble in a bubble swarm
Ziegenhein, T.
Motivation:
The lift force on a single bubble changes it sign with increasing Eo-Number
Lift formulation, Tomiyama:
πΉ_πΏπππ‘= βπΆ_πΏ π_πΏ πΌ_πΊ (π_(π΅π’π.)βπ_πΏππ ) dv_Liq/ππ₯
πΆ_πΏβ
0.6β0.1πΈπ_π» , 4β€πΈπ_π»β€8
Hypothesis: The sign change occur through vortex shedding at the bubble in a shear field
Keywords: bubbly flow; closure models; lift force; bubble column
