Evaluation of Helium Xenon Gas Mixture as Working Fluid in Highly Loaded Axial Compressor

摘要

This paper evaluates the use of helium xenon binary gas mixture having molecular weight of 15 g/mole as working fluid in an axial compressor of terrestrial nuclear power plants as working fluid. Unadulterated helium is one of the best coolant because of its prevalent transport properties, so it is hard to compress. Its utilization in high temperature gas cooled reactor (HTGR) vitality change framework lead to greater size, increasingly mass, greater expense and dynamic issues of turbomachines. In this paper a highly loaded helium xenon compressor is designed and its performance analysis is conducted. It is observed that, only 18％stages of those in helium compressor are required to compressed the gas for desired pressure in highly loaded helium xenon compressor. The compressor of high temperature gas cooled reactor (HTGR) working on Closed Brayton cycle (CBC) reduced to 2 against 16 stages. Thus, in turbo compressors of HTGR power plants, use of helium xenon over pure helium is advantageous.
