高圧条件下の二酸化炭素流動解析に関する数理モデル

抄録

Brayton cycle of CO₂ has been recognized as an attractive new method for power generations. Supercritical CO₂ is partially condensed in the compressor due to the near-critical condition. The nonequilibrium condensation model for the high pressure condition is applied to the condensation of H₂O in a nozzle and the condensation of CO₂ in a compressor cascade. The numerical result in a nozzle is in a good agreement with the experimental results. The flow of CO₂ in a cascade is condensed between the blades because of the temperature decrease.
