Drop deformation and breakup in a partially filled horizontal rotating cylinder

Drop deformation and breakup due to shear flow has been studied extensively in Couette devices as well as in gravity-driven flows. In these cases shear is generated either by the moving wall or the drop's motion. For such flows the drop shape remains unperturbed at low capillary number ($Ca$), deforms at moderate $Ca$, and can experience breakup as $Ca\to1$ and larger. Here single drops of NaOH$_{(aq)}$ will be placed in a horizontal cylindrical rotating tank partially filled with vegetable oil resulting in $10^{-2}
