Transition to Turbulence in Constant-Acceleration Pipe Flow
Abstract
The purpose of this report is to present results from the second Naval Underwater Systems Center project on accelerating flows. The main objectives of this second project were to investigate the details of the transition process and to validate the transition correlation parameters developed under the first project. The details of the transition process were investigated using the existing 5-cm-diameter test section, but with one axial location supplemented with additional wall shear stress sensors in an effort to detect the propagation of turbulence. Validation of the previously developed transition correlation parameters was accomplished by conducting constant-acceleration experiments on a new and larger 9-cm-diameter test section. Additionally, transition for mean accelerations lower than those tested previously was investigated on the 9-cm-diameter test section. Fluid mechanics, Accelerating pipe flow.
