I am currently doing my dissertation on our university’s 2017 formula student car and researching on the viability of front and rear wings for the future.
So far i have created a mesh of my initial model and have attempted to simulate it, I have had previous help to sort out little gremlins in my mesh and may look at increasing refinement levels of wheel mrf’s and radiator.
Whilst simulating, i found the force and moments continued to increase to large values which are nothing like i had previously obtained in the FSAE workshop series. I have used Turbulent and specific dissipation rate from this workshop as i have the same air velocity (20 m/s).
I have used the stl file and cad assembly to measure the wheel axis point and the rotation axis. I have used 80rad/s and 12.7324 revolutions/s to see if this was the issue (wheel diameter 0.5m).
For the porous media i don’t have the ability to calculate the d and f values and have left them to default values. I have calculated the e1 and e2 vectors, the angle of the radiator zone is 30.81 degrees from horizontal.
