Flumerfelt, Raymond W.2022-11-102022-11-10197413645431https://hdl.handle.net/10657/12590This work involves an experimental investigation of the deformation and breakup of liquid drops as well as the instability of liquid threads (both Newtonian and viscoelastic) in an extensional flow field. For Newtonian systems, it is found that Taylor's first order theory works quite well over a wider range of deformation than expected, and Chaffey and Brenner's second order theory does not provide a better approximation than Taylor's theory.
