Abstract

The stability of film blowing process has been investigated using the governing equations taking care of nonisothermal nature of the process. In this study, on top of the linear stability analysis, employing a newly-devised numerical scheme, the hitherto unavailable transient solutions of film blowing dynamics have been obtained for the first time to produce temporal portrayal of draw resonance instability strikingly close to experimentally observed profiles. Many interesting aspects of the film blowing stability have also been revealed including multiple steady states and their diverse stability characteristics.
