Time resolved Particle Tracking Velocimetry (PTV) experiments were carried out to investigate turbulent, subcooled flow boiling through a vertical rectangular channel with a heated wall. Measurements of heated wall temperature using infrared camera were acquired. Simultaneous measurements of liquid and vapor bubbles velocity were measured using PTV. In addition, the dynamic of the bubbles were studied using Shadowgraphy technique. Turbulence statistics are inferred from PTV full-field velocity measurements. Quantities such as: instantaneous 2D velocity fields, time-averaged axial and normal velocities, axial and normal turbulence intensities, and Reynolds stresses are obtained. The present results provide new information due to the full-field nature of the technique. This work is an attempt to provide turbulent subcooled boiling flow data for validation and improvement of two phase flow computational models.
