Dynamics of a Cantilevered Pipe Discharging Fluid with a Nozzle. Part 2: Three-Dimensional Dynamic Analysis and Parametric Study

摘要

It is the second part of a two-part study devoted to three-dimensional(3-D) simulations based on the mathematical model and solutionmethods proposed in Part 1. Employing the wake coefficients inFacchinetti, et al. (2004), the numerical results converge very well ifsufficient modes and proper time step-size are adopted. Simulationsutilizing newly calibrated wake coefficients in Srinil and Zanganeh(2012) are performed. Acceptable agreements are observed in both inline(IL) and cross-flow (CF) directions after comparisons withexperimental data in Stappenbelt et al. (2007). Parametric analyseshighlighting the effects of an end-mass, internal flow and nozzleinducedtension are undertaken.
