摘要: Method and apparatus for generating interfacial surfaces in a fluid mass which:(a) divide a first stream of the fluid mass into a plurality of branch streams, redirect or reposition the branch streams, expand and contract the branch streams in a symmetrical fashion, and recombine the branch streams to form a second stream of the fluid mass; or(b) divide a first stream of the fluid mass into a plurality of branch streams, redirect or reposition the branch streams, recombine the branch streams to form a second stream of the fluid mass, and expand and contract the second stream in a symmetrical fashion.
