CFD study of supercritical flow stability in two heated parallel channels with wall thermal mass effects
Nuclear Engineering and Design(2022)
摘要
•3D CFD conjugate model of supercritical water upward flow in parallel channels.•First to demonstrate requirements for successful stability analysis with wall thermal mass effects.•Flow stability predictions compare well with two experiments.•Wall thermal effects improve prediction of stability boundary and period of oscillation.•Wall thermal effects are relatively small in the case tested.
