Measurement of multi-dimensional distribution of local bubble parameters in a vertical annulus under subcooled boiling conditions

•An experimental study on a subcooled flow boiling was conducted at near-atmospheric pressure.•Multi-dimensional distribution of local bubble parameters was measured by optical fiber probes.•The flow structures in an internally-heated annulus was visualized.•The steam-water flow behavior by various...
