Abstract

The effect of intermittent re-calculation of transition position is analysed using a low-order VII platform coupled to an Orr-Sommerfeld-type stability analysis method. Transonic aerofoil and infinite-swept wing flows were studied. Where the transition mechanisms are weakly dependent on the gross flow field characteristics, as few as ten transition updates may be required over a 1000- iteration CFD solution, if correctly timed.
