World’s first exascale supercomputer shows how worn turbine blades drain jet engine power
SMRTR summary
Scientists used the world's first exascale supercomputer, Frontier, to discover how microscopic surface damage on jet engine turbine blades significantly reduces fuel efficiency and engine durability. The simulations, involving 10-20 billion grid points, revealed that tiny roughness from erosion and wear accelerates the transition from smooth to turbulent airflow, dramatically increasing heat transfer and energy losses. These findings challenge previous engineering assumptions and are helping GE Aerospace design more efficient next-generation engines with better fuel economy and reduced emissions.
