Abstract

In this investigation results of a numerical comparison between a modern turbofan under real conditions and one TPS of Deutsche Aerospace Airbus GmbH, Bremen (DA), are presented. The turbulent, axisymmetric three-dimensional engine flow is simulated numerically by using a finite-volume Navier-Stokes code. The influence of the Reynolds number on the aerodynamic quantities is demonstrated both for the actual engine and its scaled down version. The comparison of the scaled down actual engine and the simulator shows differences of the jet characteristics and the drag coefficients. The results present an insight into the possibilities and restrictions of experimental engine simulations.
