Abstract
In the present paper, we performed numerical simulations of mixed -fuel -and -air PDEs with detailed 16 8-step and reduced 10 -step reaction mechanisms. With detailed 16 8-step mechanism, one -dimensional simulations were performed to investigate the effects of hydrocarbon fuel blend s on the PDE performance. The mixed fuels consisted of methane propane, methane -hydrogen, and propane -hydrogen were studied at the a mbient conditions of 298.15 K and 0.101 MPa. Specific impulse and other properties of PDEs obtained in numerical simulations were compared with those obtained by previous analytical formulas. The numer ical and the theoretical results were in good agreement. It was found that the mixed fuel s could be evaluated for the PDE performance as well as single -component fuel s. With reduced 10 -step mechanism, o ne - and two -dimensional axisymmetric simulations of ethylene -hydrogen mixed mixtures were conducted to discuss the relaxation effect of the tube exit boundary . The n umerical results of 1-D simulations indicated that there were less than a few percent differences on specific impulse against 2-D axisymmetric results .
