The objective of this research is to demonstrate the feasibility of using acoustic pyrometry methods to take measurements in harsh, chemically reacting flow such as gas turbine engine combustion chambers. Conventional methods utilize flow invasive devices, have line of sight requirements, or use exterior parameters to measure the internal temperatures of a combustion chamber. Acoustic pyrometry methods can avoid many of these compromises and have been applied to a wide variety of industrial systems including the measurement of furnace exit gas temperatures, waste-to-energy boilers, cement kilns, metal treatment furnaces, and many other applications. The passive system works on the concept that temperature affects the speed of sound through a fluid. This work establishes that passive acoustic pyrometry is a viable option for determining combustor performance and for measuring fuel-to-air ratios and temperatures from acoustic resonances in an engine. The results include the ability to monitor temperature distributions and develop algorithms to obtain several other data sets. The work detailed includes research performed and compared with results obtained using conventional methods at NASA Glenn Research Center and Rolls Royce.

This paper is concerned with the prediction of flow and flame characteristics behind complex flame stabilizer used in aero gas turbine afterburners. The numerical calculation is performed using SIMPLE algorithm with unstructured grid arrangement in which time averaged transport equation for mass, momentum, turbulence and energy are solved using finite volume method. The turbulence effects are simulated using RNG κ-ε model. Flow analysis has been carried out for the non-reacting and reacting conditions. Meshing of the flow domain is done in GAMBIT. A detailed analysis of non-reacting flow in a 60°sector afterburner from inlet to exit of the afterburner is carried out in FLUENT solver code. The various thermodynamic properties are analyzed and presented along the length of the afterburner. Three different combustion models viz. prePDF, eddy dissipation and finite rate/eddy dissipation model are used in order to predict the reacting flow. An experimental investigation of the three-dimensional confined flow fields behind a “V” shaped complex flame stabilizer in an isothermal model of an afterburner is carried out to validate the CFD code. From the present study it is concluded that the prediction procedure adopted especially for non-reacting flow can be used with confidence in the development of an afterburner at a lower cost. Since measurements were not possible under reacting conditions no attempt has been made for reacting flow validation.
