Hello.I need help with wind tunnel.The test section is 2m x 2.5 m x 5 m long.How do I work out size of inlet cone.Thanks in advance
Wind tunnel to do smoke testing of my Formula Vee racing car
Click For Summary
SUMMARY
The discussion focuses on the design of a wind tunnel for smoke testing a Formula Vee racing car, specifically addressing the calculation of the inlet cone size based on a test section measuring 2m x 2.5m x 5m. The user has prior experience building a wind tunnel from Science Buddies and aims to scale it up for personal use. The desired wind velocity for testing is between 15 to 20 m/s, and the user questions the necessity of the contraction cone for smoke testing purposes.
PREREQUISITES- Understanding of wind tunnel design principles
- Familiarity with contraction cone calculations
- Knowledge of airflow dynamics at varying velocities
- Experience with smoke testing techniques
- Research contraction cone design for wind tunnels
- Explore airflow velocity calculations for wind tunnel applications
- Study smoke testing methodologies for automotive applications
- Investigate scaling techniques for small wind tunnel models
Automotive engineers, hobbyists building wind tunnels, and anyone interested in aerodynamic testing and design for racing vehicles.

Welcome to the PF.
What is the context of your question? What is the wind tunnel for? What do you know so far about wind tunnel design? Is this for a school project?

I know a fair amount.I have built the wind tunnel found on Science Buddies Web site.Now I want to scale that up to do smoke testing of my Formula Vee racing car.From the test section size should be able to work out contraction cone size needed.

I am 56 yrs old so not for any school project for my personal use

What wind velocity do you want to support? Can you show us what work you've done so far?

I worked out 15 to 20 m/s.As said have test section area plotted out.How important is contraction cone for only smoke testing.Do not need cd factor and drag etc.
