The component pressure losses in combustion chambers

Abstract

This Report summarises the available knowledge of the component losses in a combustion chamber. The information given in this Report should enable the pressure drops through swirlers, primary baffles, cooling systems, etc., to be calculated. Most of the data were abstracted and collected from the various reports listed in the bibliography. In certain cases (e.g.,mixing losses) the information is incomplete and in these circumstances the limited experimental results available are supplemented by hypotheses which require proof. A specimen calculation of the pressure drop and airflow distribution of a typical chamber is given in Appendix U. The calculated and measured values of pressure drop (cold) agreed within 4 per cent.
