The Stability Of Two-Dimensional Cylinder Wakes In The Presence Of A Wavy Ground, Matt Duran
The Stability Of Two-Dimensional Cylinder Wakes In The Presence Of A Wavy Ground, Matt Duran
Honors Undergraduate Theses
The following study investigates hydrodynamic stability for two-dimensional, incompressible flow past a cylinder and compares it alongside four different variations of a wave-like ground introduced within the wake region of the cylinder wake. These different variations include changing the distance of the cylinder both horizontally from the wave-like structure and vertically from the ground. The geometry and meshes were initially constructed using GMSH and imported into Nektar++. The baseflows were then obtained in Nektar++ using the Velocity Correction Scheme, continuous Galerkin method, and Unsteady Navier Stokes solver. Then, the Implicitly Restarted Arnoldi Method driver was used to retrieve the various …
Development Of Lifting Line Theory For The Fanwing Propulsion System, Christopher Kaminski
Development Of Lifting Line Theory For The Fanwing Propulsion System, Christopher Kaminski
Honors Undergraduate Theses
The FanWing propulsion system is a novel propulsion system which aerodynamically behaves as a hybrid between a helicopter and a fixed wing aircraft, and if the knowledge base with regards to this novel concept can be fully explored, there could be a new class of aircraft developed. In the current research, only 2D CFD studies have been done for the FanWing, hence the 3D lift characteristics of the FanWing have been unknown thus far, at least in the theoretical domain. Therefore, it was proposed to develop a modified Prandtl's Lifting Line Theory numerical solution and a CFD solution, comparing the …
