WebThe velocity profiles, RMS fluctuating velocity, and Reynolds stress distributions were obtained for different values of nozzle-to-plate distances e = 10 mm, 20 mm, and 30 mm. The mean axial velocity profiles obtained at low NPRs had maximum values along the jet centerline, while those at high NPRs showed the maximum velocity along the nozzle ... WebBut there are a number of machine members which are subjected to cyclic loads resulting in variable stresses that fluctuate between different levels. For example, a particular fiber on the surface of a rotating shaft, subjected to bending load, undergoes both tension and compression for each revolution of the shaft.
