Abstract
This thesis details the process undertaken to establish a method of CFD analysis for two-dimensional profiles to establish drag coefficient using SolidWorks Flow Simulation. This research was undertaken in collaboration with Canyon GmbH to be used as a method of analysis for bicycle frame design and analysis with the end goal to improving flow characteristics across a bicycle moving through airflow. Starting using a reference body of known Cd value, a methodology was defined through research to characterize mesh specifications, to create profile specific quantifiable mesh and calculation controls. These studies were namely focused on the determination of the Cd value and further the effective modelling of the expected airflow behaviour for turbulent flows, energy dissipation and frictional forces present.
The outcome from this testing was to be able to create a ‘best practice’ for 2D flow simulation for bluff bodies
