Book excerpt: The multiphysics code Spectrum(TM) is applied to calculate the unsteady aerodynamic pressures of oscillating cascade of airfoils representing a blade row of a turbomachinery component. Multiphysics simulation is based on a single computational framework for the modeling of multiple interacting physical phenomena, in the present case being between fluids and structures. Interaction constraints are enforced in a fully coupled manner using the augmented-Lagrangian method. The arbitrary Lagrangian-Eulerian method is utilized to account for deformable fluid domains resulting from blade motions. Unsteady pressures are calculated for a cascade designated as the tenth standard, and undergoing plunging and pitching oscillations. The predicted unsteady pressures are compared with those obtained from an unsteady Euler co-de refer-red in the literature. The Spectrum(TM) code predictions showed good correlation for the cases considered. Lawrence, C. and Reddy, T. S. R. and Spyropoulos, E.

This book was released on 1982 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high-frequency version of the Ballhaus-Goorjian code LTRAN2 has been adapted to represent unsteady aerodynamic phenomena in transonic cascade flow. The modifications to the algorithm for high frequencies differ from those of Rizzetta and Chin in two ways: first, a second-order difference for the jilsi (xt) term instead of a first order one is used, and second, a wake condition derived for the transonic small disturbance equation is applied. Then, in order to represent the cascade geometry, periodic boundary conditions and periodic tridiagonal solvers must be introduced. Examples of both oscillatory flows and indicial responses are presented. Application of the indicial method to unsteady cascased is discussed. Future work on the code will extend the applicability of the code to staggered, highly cambered cascades. (Author).
