Intheyear1998,thisledtothecreationofacollaborativeresearchcenterCRC557 CONTROL OF TURBULENT SHEAR FLOWS at Technische Universität Berlin, which was funded by the Deutsche Forschungsgemeinschaft (DFG) for 12 years. This CRC organized the first conference on ACTIVE FLOW CONTROL in the year 2006, followed by ACTIVE FLOW CONTROL II in 2010. In contrast to many other meetings, the interdisciplinary discussion was stimulated by the avoidance of parallel sessions. Invited lectures allowed the International Program Committee to set a clear focus and to guarantee high-quality contributions. Besides talks coming from interna- tionally renowned experts, the local CRC presented the actual results. Some of the projects of the CRC 557 were already devoted to the mitigation of thermo-acoustic instabilities that might occur in burners of turbomachines. Combing new ideas and local expertise of AFC and combustion control ended in the formulation of a new CRC proposal. This CRC 1029 SUBSTANTIAL EFFICIENCY INCREASEINGASTURBINESTHROUGHDIRECTUSEOFCOUPLEDUNSTEADYCOMBUSTIONAND FLOWDYNAMICSwasgrantedbytheDFGin2012forafirst4-yearperiod.Itallowed the CRC 1029 to announce a follow-up conference on ACTIVE FLOW AND COMBUSTION CONTROL 2014. Resulting from the new challenges faced by the CRC, the scope of the conference was extended to combustion control as well, and the namewasadoptedaccordingly.Meanwhile,theCRCisinitssecondfundingperiod organizing ACTIVE FLOW AND COMBUSTION CONTROL 2018, for which the support by the DFG is gratefully acknowledged. The successful format of the conference was v vi Preface unchanged with invited lectures and single-track sessions only. Not all presenters could prepare a manuscript for this volume, but it still presents a well-balanced combination of theoretical, numerical, and experimental state-of-the-art results of active flow and combustion control. As in the former conferences, experimental results of AFC applied to flight applications,theoreticalinvestigationsofAFC,actuators,andmodelreductionwere themaintopicsofthemeeting.Thesewerecomplementedbycontributionsresulting fromthescopeoftheCRC1029,forwhichAFCandcombustioncontrolwillhaveto be highly interlinked. The focus of CRC 1029’s research is the increase of the efficiency of a gas turbine by more than 10% by the exploitation and control of innovative combustion concepts and unsteady characteristics of a machine. The major contribution to an efficiency increase is expected from a thermodynamically motivated change from a constant pressure to a constant volume combustion. Besides the more classical pulsed detonation combustion, a shockless explosion concept was proposed in the CRC. In the meantime, this portfolio of constant volumecombustionschemesisextendedbytherotatingdetonationcombustion,for whichnewresultsaredescribedinthisvolumeaswell.Asallcombustionconcepts produce highly dynamic boundary conditions for the remaining parts of a turbo- machine,anefficiencyincreasewillonlybepossibleiftheseunsteadyeffectscanbe controlled.ItisthevisionoftheCRC1029thatthisispossiblebyAFCappliedinthe compressor,turbine,orinthecoolingsystem.Firstresultsarepresentedhereaswell.
