The key issues are focused on the design of the floats, transmission system, steering system and setting mechanism as well as the performance analysis. The graphics software SOLIDWORKS is applied to design configuration and to estimate the overall weight, center of gravity and center of buoyancy. The computational fluid dynamics software ANSYS-FLUENT is applied to simulate the free surface viscous flow field of the vehicle, and to calculate its hydrodynamic coefficients. The governing equations for these simulations are RANS (Reynolds – Average Navier – Stokes equations), while realizable κ-ε model with wall function is adopted as a turbulent model. The solver used is SIMPLE (Semi-Implicit Method for Pressure-Linked Equations). Firstly, the CFD simulation process is validated by comparing with the existing experimental data. Then the resistance of the present vehicle is determined by applying similar CFD simulation process. The results of the resistance analysis combining with proper estimation of propulsion efficiency show that the proposed detachable bicycle boat may reach a speed of 8.6 kilometers per hour for a man with power output of 300 W, which is about the average of human power of a young man. 邱逢琛 2013 學位論文 ; thesis 52 zh-TW |
