Computional fluid dynamics for combustion

Objective

The efforts of the last ten years of jet engine development has lead to increased pressure and temperature levels of the thermodynamic process in order to increase the engine efficiency. The problems arising from this development is a significant increase in pollutant emissions, especially NOx. The current technology has achieved a status that does no longer allow getting further optimisation without detailed knowledge of the physical phenomena that take place inside the combustor. The combustion process itself is governed by the reactions kinetics, the fuel preparation process, the turbulent fluid flow and the radiative heat transfer to the combustor walls. The main step of the programme is the development of physical models for CFD computations to describe the mentioned physical phenomena. The demonstration of the design criteria can only be achieved by very expensive tests under realistic engine operating conditions. The only method to reduce costs is the reduction of the number of experiments by accompanying the experiments with 3D-calculations of the reacting flow inside the combustor.
