Please critique my dynamic driver based FLH Hornresp simulation

[Giri]

I simulated an FLH driven by a couple of dynamic drivers in series. Please let me know your comments and opinions.
Thank you.

The specified throat area of 0.18 cm^2 (4.24 mm x 4.24 mm) is not realistic.

For one thing, it results in a Sd / S1 compression ratio of more than 300 to 1 🙂.

I merely calculated the throat area such that the throat perimeter is equal to the wavelength at 20000Hz 🙂
What is an acceptable throat area and ratio for this simulation?

The throat velocity shows supersonic speeds. What does that translate to, in real life?

Destruction of the drive units. 😉

I just noticed that 2 drivers have been specified, meaning that the compression ratio would be greater than 600 to 1.

A ratio of about 4 to 1 would be more realistic.

Understood!
