Description
High-power accelerators intended for space require more efficient cooling technologies. Flow boiling, a two-phase process, where water is boiled to dissipate the heat reduces size, weight, and power (SWaP) of thermal control systems (TCS).
The purpose of this work is to understand the flow and bubble dynamics of two-phase flows designed for space TCS. We present the experimental setup to measure velocity, temperature, and bubble dynamics at a spatial resolution of 5 μm/pixel in a 5 mm x 2 mm channel with one-sided heating. The setup includes three high resolution cameras for PIV (Particle Image Velocimetry), PLIF (Planar Laser-Induced Fluorescence), and shadowgraph to take measurements of velocity, temperature and to capture bubble images respectively. The raw and post processed data surrounding the bubbles generated in the flow is presented for the first time, showing the correlation between flow dynamics and heat transfer.
