J0520302 Transonic Flow Simulation of Supercritical CO_2 Through a Compressor Cascade

Supercritical CO_2 has been recognized as an attractive new method for power generation. In this system, Supercritical CO_2 is compressed and heated beyond the critical pressure and temperature. In this study, transonic flows through a compressor cascade are investigated under the supercritical pressure condition by our numerical method. A detached bow shock is found near the leading edge and a normal shock is captured between the blades. The results are compared with those of the atmospheric condition.
