Abstract

This paper presents numerical simulation results of hydrogen combustion in variable flow ducts. The study was carried out in three-dimensional formulation using the chemical kinetic mechanism. Several configurations of the flow paths were examined. Relative thrust and combustion efficiency were selected as criteria for comparing the flow ducts. The results of the numerical simulation were compared with the results obtained within the framework of a one-dimensional calculation. The presented results can be used at the calculating stage of the operational process in the advanced power units.
