- •
Experimental studies of the most ‘dangerous’ heater location are conducted.
- •
Nonlinearity is identified experimentally.
- •
Transient energy growth and modal analyses are performed.

Good agreement is obtained between experimental and theoretical results.
- •
Rayleigh index is determined as an indicator of the heat-to-sound coupling.
