I am currently testing the coefficient of drag on two variables and one constant. The simulation is based on a front bicycle wheel traveling at 12.5m/s. Outlined below are the test variables and constant (currently only Variable_1 has been tested).
Constant : Wheel without anything on it
Variable_1 : Wheel with an aerodynamic weight
-Variable_2 : Wheel with blue tack, or weight strips
My question is should I input the specific center of rotation for each system i.e constant, varialbe_1, and variable_2, or should I keep the center of rotation constant for every system?
The coefficient of drag results have been produced using an ‘MRF rotating zone’, ‘Topological entity’ and ‘Force and moments coefficient’. I am assuming these are all correct parameters to be using?
Thanks for the support.
