Scientific paper

A 1.5-dimensional numerical code is used here to analyze the evolution of large-scale expanding shells generated by winds and supernovae from OB associations and embedded in differentially rotating galactic disks. The results of these numerical experiments are fitted by a set of relationships which provide the evolution in size, shape, position angle, and matter swept up by the evolving large-scale structures. These relations are used to derive the properties of some observed remnants in M31 and M33.
