Assume that I am running an aerodynamics simulation for air with the following properties:
- 20 degrees celsius
- Wind speed of 5 metres per second
- Pressure of one atmosphere
For any other important property I have left out, assume average back yard conditions in a temperate geographical zone.
I know that air is a mixture of molecules that have translational, rotational and vibrational energy components.
My question is, for the conditions described above, how big is the translational energy component, compared to the other two?
An answer which calculates all three components for the conditions described and gives numbers would be ideal.
How does this change if the wind speed is zero?
My reason for asking is that I wish to write my own simulation which models gas as a collection of particles that have purely translational energy, ie. an xyz velocity to keep things simple.
I'm well aware of the challenges of doing this from a computer science point of view and I do not wish this to turn into a discussion of the technicalities around that. My question is purely to do with the physics.
This has been edited as I realise my original question was too programming oriented and therefore misleading.
