dc.description.abstractThe Atlantis Intake System (AIS) is a novel design for a ramjet inlet intended to produce thrust through a wide range of flight Mach numbers, including at static conditions, by operating as an ejector-ramjet. A computational fluid dynamics study is performed to assess the change in performance of the AIS due to preheating the fuel jet using heat released from combustion. However, first the computation model is assessed for several combustion-related problems relevant to an ejector ramjet: a one-dimensional laminar flame, a three-dimensional bluff-body stabilized flame, and a ramjet with the AIS operating at static conditions. For an ejector ramjet, preheating the fuel jet is shown to increase the ratio of air to fuel entrained by the AIS and the specific impulse (ISP). Furthermore, if the global equivalence ratio is above unity, preheating the fuel jet while keeping the fuel jet stagnation pressure constant results in an increase in thrust. In contrast, the thrust is lowered as the stagnation temperature of the fuel jet is increased for cases with lean combustion if the stagnation pressure of the fuel is kept constant.
