Abstract

Abstract: The present study is concerned with the formation and detachment of polymer solutions pendant drops initially attached to immersed needles in Newtonian mineral oil. Drop formation, pinch-off and detachment is studied in two cases: (i) one single needle placed vertically and (ii) two needles placed horizontally opposite to each other. In the second case, the interface meniscus presents an elongated shape near the two needles and oscillations of this interface are observed. These are associated with the drop detachment.
