TL;DR: In this article, a series of geometry path continuous adjustment experiments and numerical simulation were conducted in the variable geometry dual mode combustor with a Mach number of 3, a divergent ratio ranging from 1.6 to 2.54 and a fuel equivalence ratio between 0.6 and 1.0.

TL;DR: In this article, the authors investigated the mechanism of combustion performance loss for the variable geometry dual-mode combustor and found that for a given fuel equivalence ratio, the wall static pressure, total pressure recovery coefficient, combustion efficiency and thrust increased with the decreasing of divergent ratio.

TL;DR: In this article, the effect of the deflection angle on combustor performance of a variable geometry dual mode combustor, the flow field characteristics and mechanisms of the combustors performance loss, which comprised of compression loss, combustion heat addition loss and expansion loss, were investigated in the variable geyser dual-mode combustor numerically with a Mach number of 3, a divergence ratio of 1.76, a fuel equivalence ratio of 0.6, and a deflection angles ranging from 8° to 16°.

TL;DR: In this article, a direct-connect experiment with equivalence ratio linear increasing in a dual-mode combustor with a strut is conducted at free stream Mach number of 2.0, and a typical simplified geometric model is proposed and studied by using numerical simulation.

TL;DR: In this paper, the effect of heat release on movement characteristics of shock train is numerically investigated in an isolator, and it is found that the combustion heat release has a distinct effect on the shock train movement characteristics in the isolator.
