    Abstract: Apparatus for forming and fibrillating a molten polymeric film into nanofibers consisting of a plurality of two-phase flow spinning nozzles arranged in a substantially liner array each nozzle into nanofibers including one or more first input orifices for a process gas; one or more second input orifices for a polymer melt; a flow channel including two or more channel walls and a monotonically decreasing flow area wherein the process gas and polymer melt are combined into a stratified two phase flow with the polymer melt formed into a film on one or more of the channel walls; and one or more channel exit openings, each exit opening including an edge at which the process gas reaches sonic velocity or less and where the edge is configured to fibrillate the polymeric film into a stream of nanofibers.
