Book Description
A measuring technique based on multisensor hot-wire anemometry has been developed to determine the unsteady three-dimensional velocity vector and the structure of turbulent flows. It then has been applied to the passage and the exit flow of an annular compressor cascade, which is periodically disturbed by the wakes of a cylinder rotor, located about 50 percent of blade chord upstream. In Part I of this paper the decay of the rotor wakes has been described first without stator and secondly through a stator passage. The time-dependent turbulent flow field downstream of this stator is discussed in Part II of this paper. The rotor wakes have a major influence on the development of three-dimensional separated regions inside the compressor cascade, and this interaction will be addressed in both parts of the paper.

Book Description
The flow velocity in an axial compressor, with a distorted inlet pressure profile or rotating stall cells, is unsteady in both magnitude and direction with the unsteadiness in direction having a more abrupt effect on airfoil performance. The objective of this research was to obtain pressure distributions and pressure histories on both surfaces on an airfoil in a cascade while its is undergoing a sinusoidal variation in angle of attack.
