dc.description.abstract | Circular cylinder is of vital importance in the marine industry. The goal of this thesis is to study
the physical phenomenon around the inclined circular cylinder as well as the forces acting on
it. The study is mainly divided into three parts. The first part is used to perform 2D circular
cylinder simulation. The purpose of part one is to find a series of proper parameters and prove
the independence of grid in two-dimensional plane. The second part is 3D simulation of vertical
circular cylinder at Re = 300 and 500. The 3D mesh is obtained by extruding the 2D mesh into
different span-wise height. Results are discussed in terms of force coefficients and physical
quantity plots. The effects of cylinder height and different boundary conditions on top and
bottom boundary are compared and studied. The third part mainly focuses on the simulation
of inclined cylinder with different inclination angle which changes from 0± to 30±. The physics
phenomenon around inclined cylinder has been studied and the principle of the forces variation
pattern with different inclination angle and different Re number has also been summarized. | en |
