Abstract:
This paper deals with the perturbation induced by the gauge pressure alongside a combustion chamber. This perturbation is modeled by acoustic pressure, measured at the end of the combustor. These vibration modes are obtained experimentally using Fourier Analysis. The analytic model of Pressure Distribution Equation (PDE) on can combustor is based on a wave equation. This paper describes the procedure that was carried out to obtain the temperature of a column of hot air inside a simple combustor. The Rijke tube was used with the aim of laying the foundations of a future thermoacoustic phenomenon analysis. The contribution of this work is spatial interpretation of pressure waves and displacement in a chamber during thermoacoustic phenomena.
