Secondary loss prediction methods
Abstract
Secondary flow effects on turbine performance are recalled, and prediction of losses by correlation and secondary flow theory methods is discussed. Neither approach is satisfactory, since, in the machine, blade row interference, radial flows, tip clearance, and walls with steps, grooves, gaps and flare modify secondary flow.
