abstract

Since the instantaneous phase-averaged flow field has been characterized and properly described through both numerical and experimental studies in a single stage axial flow blower, the next step is to identify the sources of unsteadiness related to blade passing frequencies. The construction of the deterministic stress tensor in both rotating and fixed frames of reference, through a sequential averaging technique, is extremely useful for this purpose. This kind of tensor shows the location and intensity of the main interaction characteristics of the flow, allowing a perfect segregation of the effects of every blade row onto the total unsteady scenario of the complete stage. The steady signature of the stator wakes, still present at the exit plane, downstream the forward rotor, will be related to the residual deterministic kinetic energy of the mixed-out flow. The migration of these unsteady features onto the averaged flow field will be used to understand the recovery process that occurs when the flow passes through the rotor of the stage, linking flow physical phenomena with the transport and convection of the deterministic stresses.
