Drop shapes emerging at very low flow rates from thick-walled cylinders

A. López-Villa, A. Medina, C. A, S. López, C. Duran


In this work we study the equilibrium shapes of drops that emerge slowly outside of vertical, thick-walled tubes. For low flow rates it is possible to calculate drop shapes by using the balance equation between the hydrostatic and injection and capillary pressures. Through the use of image processing software were obtained the center of mass and volume of the experimental drops and the qualitative agreement between our experimental and theoretical results is very good.
