Abstract

A companion paper presented by the A. Schock et al. (see ibid., p.1156-64, 1997) described an OSC-derived methodology for the coupled thermal, fluid flow, and electrical analyses of AMTEC cells with multiple Beta Alumina Solid Electrolyte (BASE) tubes, and illustrated its application to a specific cell design. This paper describes parametric results obtained by applying the same procedure to 39 variations of that cell design to determine the effect of 24 individual design variables on cell performance. For each of the 24 design variables, OSC performed detailed analyses of two designs that were identical except for that variable. This served to isolate the effect of that variable on the cell's power, efficiency, and critical temperatures. The paper presents the results of those analyses, and explains the reasons for the design decisions made by OSC. Subsequently, it describes the results of parametric analyses to determine the effect of temperature margin, input thermal power, and output voltage on the cell's critical temperatures and performance.
设计变化对AMTEC电池效率的影响,以及操作参数对OSC电池设计性能的影响
A. Schock等人发表的一篇配套论文(同上,第1106 -64页,1997年)描述了一种osc衍生的方法,用于对带有多个Beta氧化铝固体电解质(BASE)管的AMTEC电池进行耦合热、流体流动和电分析,并说明了其在特定电池设计中的应用。本文描述了通过将相同的程序应用于该电池设计的39个变化来确定24个单独设计变量对电池性能的影响而获得的参数结果。对于24个设计变量中的每一个,OSC对除该变量外完全相同的两个设计进行了详细分析。这有助于隔离该变量对电池功率、效率和临界温度的影响。本文介绍了这些分析的结果,并解释了OSC做出设计决策的原因。随后,描述了参数分析的结果,以确定温度裕度、输入热功率和输出电压对电池临界温度和性能的影响。
