Major topics for Turbomachines 2018 conference include, but are not limited to:


aeroelasticity issues induced by low or part-load operation, dynamic response of the rotating blades with respect to aeroelasticity, stall and un-stall flutter, flutter resistant ST and GT blades

Optimization of turbine components limiting ST and GT flexible operation

bearings, seals, etc. for flexible operation of ST and GT

Life cycle management

fatigue damage induced by high and frequent transient loadings, lifetime utilization of critical turbine components, low cycle fatigue, thermo-mechanical fatigue, creep-fatigue interaction, residual life prediction, lifing methods

Turbo machine diagnostics and analytics

whole engine and whole plant modeling, monitoring and optimization of turbine and/or plant operation, online analytics and monitoring, blade tip-timing
