Abstract

The code PIANO, developed at the Institute of Aerodynamics and Flow Technology (Dept. Technical Acoustics), is designed to simulate aeroacoustic noise generation and acoustic wave propagation in non-uniform flows. It is based on the equations governing the inviscid dynamics of perturbations to a given time-averaged mean flow field. PIANO simulates the noise generation process, when vorticity interacts with solid structures or gradients in the flow field. PIANO is not designed to calculate wave propagation over very large distances in uniform flows, like from aircraft to ground. In that case methods based on wave equations are more appropriate. Currently, PIANO is based on structured, curvilinear multi-block grids. The coding structure is designed for high performance on workstations, vector machines, PCs or PC clusters as well. PIANO is a research code.
