MECHANISM OF PARTIAL METAL MELT STRATIFICATION IN CAPILLARS

Abstract

Experimental results of diameter, inclination, angle and length effects on metal melt stratification rate are represented. These relationships determined experimentally were compared with relationships obtained on the basis of simple hydrodynamics expressions. It has been approved that mechanism of the layering is not related with convection inside metal sample. Experimental data and theoretical evaluation show that most adequate explanation of the stratification process can be produced with the assumption of special properties of single-atom surface layer of liquid melt having characteristics of ideal gas in interphase space between capillary inner wall and liquid sample.
