Wind tunnel

The experimental work in high school physics is basic principle of education. Established tasks sometimes aren't challening enough  for young researchers.

For current industry and laboratory research, wind tunnel is an important form of testing and measurement. This form of testing is essential in the automotive and aerospace industries.

In the school year 2013/14, we decided, along  with students, to prepare a wind tunnel, which will serve as experimental work in physics education.

Operation of the wind tunnel

We will try to answer the following questions and complete following tasks:
- Determine the optimal measure of laboratory wind tunnel.
- Select materials for construction.
- Dimensioning drive air flow.
- Decide how to ensure a steady continual distribution of air flow through the section of the wind tunnel.
- Identify the method of measuring air velocity in the device.
- Try out some of the old methods measuring, which are based on a change in pressure.
- Establish measurement with digital anemomometrom (Vernier).
- Establish a mechanism for transmitting the measurement for forces in two coordinates.
- The measurement forces in x-y with digital sensors.
- Computer data processing (Logger Pro).
- Find the technology to see the wind lines.
- Design and construct in the program SkenchUp.

October, 2013. 
Students are invited to attend the design and manufacture measur - the experimental device. The work will take place in the physics lab (109). Please get in touch without commitments. Students who would like to prepare a research paper and present it at a Meeting of young researchers of Slovenia, can sign up for this additional activity.  All those interested can get more information from of Physics teacher (J.Pernar)  joze.pernar@guest.arnes.si.
