For the thermal design of combustion chambers and turbine blades in jet engines, a detailed knowledge of the combustion and heat loads to the walls is necessary. A new test bench was set up to study the chemical near-wall reactions under atmospheric pressure. The preliminary results of gaseous, nonpremixed near-wall CH4/air and H-2/air flames were analyzed using optical methods and inverse heat conduction calculation.
For the thermal design of combustion chambers and turbine blades in jet engines, a detailed knowledge of the combustion and of the heat loads to the walls is necessary. In general, high operating temperatures and reduced combustor size are striven for in order to increase engine efficiency and reduce weight. Consequently, the components are exposed to temperatures above the melting point of the materials and there is a growing risk of incomplete combustion within the combustion chambers. To study these effects, we setup a new test bench for fundamental investigation of chemical near-wall reactions at atmospheric pressure. First results of gaseous, nonpremixed near-wall CH4/air and H-2/air flames are presented. Optical methods such as two-line laser-induced fluorescence thermometry and OH* chemiluminescence were applied. Further, the heat release to the wall was determined by means of inverse heat conduction calculation using the data of implemented thermocouples.
