Influence of the wall on the boiling regime

Research output: Contribution to journalConference article

Abstract

This work is devoted to investigation of wall roughness and its thickness. It is not enough to know the heat flux and the physical properties of the liquid for determining the boiling mode. The wall roughness and its thickness also plays an important role. Changes in the surface roughness from 5 to 7th grade did not affect the behavior of the curves. The width of the transition region for the boiling crisis is much less for the polished surface (roughness grade is 9) compared to the rough wall. The boiling crisis for mirror wall comes at a lower overheating of the wall. The total time of evaporation on the mirror wall is almost 3 times higher than for a rough wall.
