Abstract

The unsteady flow which is generated when 2 turbomachinery blade-rows are in relative angular motion is periodic in time with a different period in the frame of reference associated with each blade-row, and is characterized by a pitchwise traveling wave chorochronic periodicity. This periodicity is studied for arbitrary angular velocities and pitch-ratio of the 2 blade-row and simple formulae for the corresponding interblade-phase angles are given.
