- TL;DR Summary
- CFDs or pre-written codes that would help measure the effect of vent ratio on drag coefficient of parachutes.
For my 12th grade school project, I'm planning to research on the effect of vent ratio on the drag coefficient of round parachutes. My idea was to make small model parachutes and drop them from a height, and derive the drag coefficient after certain assumptions. But I also thought it'd be interesting to build a wind tunnel and compare the results from both experiments. However, I'm not sure how to collect drag values from a home made wind tunnel. I'd also like to use a virtual wind tunnel or CFDs to obtain more accurate results and compare my experimental data. Are there any easy CFDs using which I can model round parachutes or any pre existing code that could achieve the same purpose? I'm planning to focus on the effect of the round parachute while descending, not during inflation as it would complicate the process.
