Characteristics of lightly loaded fan rotor blade wakes

摘要: Low subsonic and incompressible wake flow downstream of lightly loaded rotor was studied. Measurements mean velocity, turbulence intensity, Reynolds stress, static variations across the at various axial radial locations were investigated. Wakes measured blade incidences to discern effect loading on wake. Mean velocity measurements carried out with a triaxial hot wire probe both rotating stationary behind rotor. Results indicate that increased slows decay rates tangential defects velocities in The presence large extent interactions between one radius another. Appreciable pressure found near region. Similarity profile shape for components outer layer axial, tangential, intensities.
