Prediction of shell response and wall-pressure fluctuations in turbulent single and two-phase flows
Abstract
A mathematical model is presented of a cylindrical shell subjected to wall-pressure fluctuations induced by a fully developed boundary-layer in two-phase flow. To this end, the shell is subdivided into a number of cylindrical finite elements, each with two nodes, the nodal displacements being the axial, circumferential, and radial displacements and rotation. The pressure field is similarly rendered discrete, being represented by two forces and a moment at each node. The theory is applied to experimental predictions of the statistical properties of the wall-pressure field and the shell response. The predicted shell response is compared with that determined experimentally.
