Abstract

This paper discusses numerical simulations of fore and aft noise radiation from turbofan engines. Three different approaches are considered. These are based on the explicit solutions of the full Euler equations, Euler equations linearized about a nonuniform background flow, and the frequency space form of the linearized Euler equations with nonuniform flow, respectively. Issues related to the fan-face inflow and outflow boundary conditions are discussed, and results from the three methods are presented and compared.
