Effect of heat conductivity and thickness of substrate on thermocapillary rupture of locally heated horizontal liquid film

Effect of heat conductivity and thickness of substrate on thermocapillary rupture of locally heated horizontal liquid film

Experimental results on thermocapillary rupture of a horizontal locally heated water film on the removable substrates of different thicknesses, made of materials with different heat conductivity, are presented in this paper. The studies have shown that with an increase in substrate heat conductivity...
