摘要

摘要: 针对现有的动力电池、柴油-液氧型斯特林机等常规水下动力系统的能量密度多在300 W·h/kg以内的问题, 提出了一种以铝粉燃烧为基础的新型高能量密度斯特林水下动力系统方案。通过数值仿真方法, 分别构建了铝水燃烧联合燃氢斯特林机水下动力系统以及铝水燃烧+氢氧燃烧联合液钠斯特林机水下动力系统, 并与传统柴油-液氧斯特林机动力系统进行了能量密度以及燃料成本的比较。结果发现, 铝水燃烧联合燃氢斯特林机水下动力系统的能量密度高达648 Wh/L, 为传统柴油-液氧斯特林机动力系统的2倍, 燃料成本为传统柴油-液氧斯特林机动力系统的2倍; 铝水燃烧+氢氧燃烧联合液钠斯特林机水下动力系统的能量密度为传统柴油-液氧斯特林机动力系统的1.7倍。可见, 新型闭式铝粉燃烧斯特林水下动力系统有着良好的发展潜力, 可为未来水下动力系统的设计提供理论参考。

Abstract: To increase the energy density of conventional underwater power systems, a new type of high energy density Stirling underwater power system based on aluminum powder combustion was proposed. An aluminum-water combustion plus hydrogen combustion Stirling underwater power system and an aluminum-water combustion plus hydrogen-oxygen combustion combined with liquid sodium Stirling underwater power system were built by numerical simulation. The energy density and fuel cost of the two new systems were compared with those of conventional diesel-liquid oxygen Stirling power system. Numerical simulation results show that the energy density of the aluminum-water combustion plus hydrogen combustion Stirling underwater power system is 648 Wh/L, which is two times that of the conventional diesel-liquid oxygen Stirling underwater power system, and the fuel cost of the former system is also two times that of the latter one; the energy density of the aluminum-water combustion plus hydrogen-oxygen combustion combined with liquid sodium Stirling underwater power system is 1.7 times that of the conventional diesel-liquid oxygen Stirling underwater power system. As a result, the new type of closed aluminum powder combustion Stirling underwater power system has good application potential in the future underwater power system.
