I'm currently playing with a school project.
My goal here is to heat a stream of air to a significant temperature so I can demonstrate air expansion.
I have a cylinder, with a few turbines, turning in opposite directions, into another cylinder in the shape of a nozzle. My goal here would be to use the second cylinder, to place a heating device. As air would compress, it would suddenly expand with heat.
Not an over engineered machine, just something that does the trick.
So beside security, my question is what is the most efficient way to heat air through a cylinder? What type of material should i use to both conduct/insulate?
One additional question would be: Does an OverPowered Iow Wind Coil would do?
Feel free to leave some of your knowledge or experiences on this matter, I'm collecting data as we speak, and some clear minds already geared on the subject are always welcome to leave their input.
Have a great day, and bless ya
