Abstract
Liquid inlet behavior to a heat surface in micro-bubble emission boiling (MEB) was investigated by PIV measurement. Subcooled pool boiling experiments were performed using a heat surface with a diameter of 10mm. An upper end of a heater block was used as the heat surface. The subcooling was varied from 40 K to 70 K. The flow visualization around the heat surface was carried out using a high speed video camera and a light sheet. The micro-bubbles generated in the MEB were used as tracer particles and the velocity field was obtained by PIV analysis of the acquired image sequence. The distribution characteristics and fluctuation of the velocity were studied.
