Extended Parametric Modeling of Transition Tube with Constant Section Area along Arbitrary Central Routes on CATIA

Extended parametric models of transition tube structures were implemented based on authors previous work [11] on constant cross section area assumption along arbitrary central routes like straight, circular and oblique curves on CATIA platform. It is aimed at that these structures can provide more flexible geometric configuration options and modifications to tube channel transitions for multi phase flow systems and pipeline junctions. Details of parameterized modeling process were exhibited on CATIA Generative Shape Design module with the help of Parameters and Relations functions. The tube surface models are all in circular cross sections and constrained in many ways along arbitrary coplanar or cylindrical sub-central routes three dimensionally for various layouts. Future work is emphasized on numerical simulation and experimental investigation with these geometric structures in multi phase flow systems and pipeline application.
