Use of STAR CD for viscoplastic flow


  The aim of this study is the observation of fluid's behaviours. In the following report, one will study the Poiseuille flow of a Bingham viscoplastic fluid. The flow occurs in a channel and one will study velocity profiles to see the Poiseuille profile.

        At first, one will study an air flow and a water flow. Then, one has changed the STAR CD code to introduce a behavior law. The aim of this modification is to simulate the behavior of a viscoplastic fluid, the fluid of BINGHAM.

        A theoritical part gives us the general equations system that describes the movment of a fluid with general properties. Then, one see the theoritical part about the Bingham behavior's law. Then, another part shows us the obtained results for each treated case. These pictures will be commented in function of the theorie previously seen.
