Economic Analysis of 3D-Printed Ceramic Cores for GasTurbine Investment Castings
When manufacturing blades and vanes for gas turbine engines, internal cooling channels are formed by investment casting with sacrificial ceramic cores. The hot injection and pressing techniques traditionally used to manufacture ceramic cores have long lead times and high up-front costs, motivating …

Strukturanalyse turbulenter Flammen mit Hilfe abbildender laserspektroskopischer Verfahren
… da z.B. thermoakustische Schwingungen in Gasturbinen zu verstärkter Materialbeanspruchung führen. Dies stellt auch im Bereich der Flugzeugturbinen eine erhebliche Gefahr dar. Numerische Simulationen erlauben, die Prozesse bei der Verbrennung besser zu verstehen, jedoch sind Direkte …

Effect of wall motion on a two-dimensional turbulent boundary layer
… stator and rotor blades for a single stage in a gasturbine engine. Mass transfer results on the suction surface of the blade suggest that the onset of the secondary flow region near the endwall moves upstream with the belt motion. This is probably due to the lifting of the passage vortex by the …

Novel Conceptual Design And Anlysis Of Polymer Derived Ceramic Mems Sensors For Gas Turbine Environment
Technical challenges for developing micro sensors for Ultra High Temperature and turbine applications lie in that the sensors have to survive extremely harsh working conditions that exist when converting fuel to energy. These conditions include high temperatures (500-1500°C), elevated pressures …
