Measurements of vapor fraction and bubble axial velocity were carried out in subcooled boiling flow using a newly designed two-sensor fiber-optic probe. The sensors encountered the axial motion of the vapor bubbles essentially head-on. The new measurements were more repeatable and had less scatter in the outer low vapor fraction region of the boiling layer compared to our earlier measurements.
