Background
The high-density liquid fuel is a common power source of the hypersonic aircraft, and the energy characteristic of the high-density liquid fuel is a key for improving the performance of the hypersonic aircraft. The energy density of the traditional liquid hydrocarbon fuel is low, and the requirement of the current aircraft for rapidly improving the performance is difficult to meet. The boron-based suspension fuel can greatly improve the theoretical energy density of the liquid hydrocarbon fuel by adding high-energy boron particles into the liquid hydrocarbon fuel, thereby effectively meeting the requirement of an aircraft on the fuel energy performance.
The boron-based suspension fuel mainly comprises high-density liquid fuel and boron particles suspended in the high-density liquid fuel, and the combustion process of the boron-based suspension fuel relates to evaporative combustion of hydrocarbon fuel and ignition combustion of the boron particles. Although the fuel has excellent theoretical energy density, in the actual combustion process, due to the problems of high oxygen consumption of liquid hydrocarbon fuel and difficult ignition of boron particles in a low-oxygen environment, the energy of the fuel is difficult to be efficiently released, so that the advantage of high energy density of the fuel is difficult to exert. As the combustion process of the boron-based suspension fuel is the synchronous oxidation combustion of solid-liquid two energetic components, the two components have a synergistic competition relationship. Therefore, in order to realize the sufficient energy release of the fuel, the oxidation combustion of solid-liquid double components in the fuel needs to be synchronously strengthened, so that the energy of the solid-liquid components in the fuel can be sufficiently released, and the actual combustion heat value of the boron-based suspension fuel is further improved.
In the existing research, part of single-component combustion promoting means related to hydrocarbon fuel and boron particles can be seen, but the single-component combustion promoting means is not strong in applicability to a boron-based suspension fuel containing solid and liquid components at the same time, synchronous strengthening combustion promoting of oxidation combustion of the solid and liquid components of the boron-based suspension fuel cannot be realized, and the exertion of the energy density advantage of the boron-based suspension fuel is severely restricted.
Metal oxides, e.g. CeO2And the like, has higher oxygen storage-release capacity and oxidation-reduction performance, and is widely applied to the field of oxidation reaction catalysis. The oxygen activation transfer network is constructed on the interface, so that the oxygen transfer rate in the fuel combustion process is improved, and the oxidation reaction energy barrier is reduced, so that the high-efficiency energy release of the fuel is promoted, and the fuel has a good combustion promoting effect on the oxidation combustion of solid-liquid fuel.
