By combining the vortex lattice and panel methods with a mixed boundary condition, it allows efficient exploration of design options. The method also models tip-leakage flow through an iterative algorithm. A periodicity condition is validated, reducing computational demand, with calculations completed in under a minute. The method agrees well with RANS for mean flow and tip-leakage characteristics, though some discrepancies arise at lower mass flow rates.
