Behaviour of acoustic waves in a duct with Helmholtz resonator in presence of a temperature gradient [PDF]
Understanding the behaviour of one-dimensional acoustical wave propagation in ducts is very important for controlling combustion instabilities in propulsion, household burners, gas turbine combustors, and designing engineering mufflers.
