Résumé
This work explores application of an idea called `Path Homotopy' from Topology in twin screw compressor rotor profile design. It is well known that twin screw rotor profiles impact the overall performance of screw compressors to a great extent. Almost all the well known profiles that are commercially used in twin screw compressors are generated out of analytical curves such as circles, lines and conic sections. Analytical representation has its own advantages in profile design but it limits the search space of all possible shapes that can be incorporated in profiles. This work aims at proposing an approach for rotor profiling that sticks to the analytical nature of curve representation in profiles while simultaneously extending the search space of curves that can be deployed in the design. Path homotopy has been identified as one of such approaches. Profile elements can be defined as homotopies between well known analytical curves (circles, lines and conic sections) and the homotopy parameter can directly inuence these curves morphologically in their analytical form itself. In this way, shapes other than those used traditionally in profiling can be explored in search of the better rotor profiles.
