Summary: Direct Numerical Simulation of Turbulent Flow around a Rotating Circular Cylinder Turbulent flow around a rotating circular cylinder has multiple applications but, uniquely it can be applied to convex surfaces, so that flow-affected corrosion with high Schmidt numbers can be modeled. Despite the positive attributes of modeling this way the curvature of the cylinder affects the turbulence structure and creates a two- dimensional homogenous flow. These to factor when paired together decrease the detail of flow field over the geometry on which corrosion is to be predicted, and because little is

Unformatted text preview: known about this turbulence and it is tough area to model, the only option for this model is to use direct numerical simulation (DNS). In DNS parameters are set and a computer is used to model physical objects in real-world situations. For the purpose of this experiment the a cylinder radius, outer boundary, axis of rotation, and spanwise size were set as the parameters. The only varying parameter was spanwise which was larger at higher rpm’s to contain the turbulence....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
