Experimental study of pool-boiling heat transfer augmentation by ultrasonic.

[ In Korean. / En coréen.]

Author(s) : KIM D. H., CHOI J. Y., KWON Y. C.

Summary

The experiment is performed with the subcooling temperature of 0, 10, 20, and 30°C and the inclined angle of 0°, 10°, 20°, 30°, 60°, 90°, 120°, 150°, and 180° and the ultrasonic power of 300 W, 600 W. From the experimental results, it is found that ultrasonic effect enhances CHF of the plate. As increasing the degree of subcooling, the rate of CHF increase is enhance. As increasing the inclined angle, the rate of CHF increase decreases. Also, the authors can see that the heat transfer mechanism of CHF augmentation is closely connected with the dynamic behaviour of bubble generation and departure.
