"The industrial gas turbine and military engine manufacturers have astrong need for accurate design tools that are capable of predictingaeroengine combustion, as well as predicting the sensitivity of the flowto a wide range of engine design parameters including actuator power andfuel-injector location. In response to this need, AeroSoft, incooperation with Virginia Tech, propose to experimentally test adynamically scaled combustor where the flame is stabilized behind abluff-body combined with a dump. Parametric studies from steady,unsteady and open-loop control operations will be used to measure thefidelity of computational simulations. An additive semi-implicitRunge-Kutta scheme and a two-parameter coupling mechanism will beimplemented to compute the bluff-body instability problem. Thesensitivity-equation method will be incorporated into a time-accurateflow solver to provide truly unsteady sensitivities to various actuatorparameters. The combined experimental/computational work provides anopportunity to further the development of distributed-parameter controlin combustor applications."
