Convective boiling heat transfer under microgravity and hypergravity conditions

•Heat transfer data for flow boiling under micro, hyper and normal gravity conditions.•Two-phase flow images under micro, hyper and normal gravity conditions.•Comparison of prediction methods and experimental data for flow boiling heat transfer.•Gravitational acceleration affects two-phase distribution, drift velocity and pressure drop.•Constant pressure gradient is not reasonable for the data regression analyses.
