AI Thread Summary
CFD can effectively predict airflow around vehicles and the trajectories of objects ejected from them, influenced by the vehicle's shape, speed, and the object's characteristics. Practical experiments may pose legal risks, such as littering charges. Constructing a wind tunnel is a suggested alternative for testing airflow dynamics. The discussion also references the finite element method as a relevant computational approach. Utilizing free and open-source CFD software can aid in these simulations and analyses.

Trying to evaluate airflow around a vehicle and behind it to calculate where an object would rest after leaving driver side window.

Welcome to PF.
It will depend on the shape and speed of the vehicle, and the characteristics of the object and the launch trajectory.
If you carry out the practical experiment you may be charged with littering.
Have you considered building a wind tunnel ?

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
