Turbulent heat transfer in a flow of liquid metals

Experimental Determination of the Turbulent Prandtl Number in a Developing Temperature Boundary Layer

“…This is represented by the two separating bands in Fig. 1 Measurements of the turbulent Prandtl number for liquid metals have also been conducted by Subbottin et al [157] and Buhr et al [158], Their results show distributions of Prt similar to those presented in Fig. 1.1 for liquid metals.…”

CONDENSATION OF METAL VAPORS: MERCURY AND THE KINETIC THEORY OF CONDENSATION (thesis)

“…(28)(29)(30)(31)(32)(33)(34)(35) Noncondensible gases can impose a significant resistance to condensation. (1,9,(36)(37)(38)(39)(40) Sparrow and Lin(41·) analytically described film condensation in the presence of noncondensible gases to show the importance of gas diffusion normal to the surface and free convection parallel to the condensate surface.…”

“…This resistance is generally believed to be caused by solid-surface contamination and/or by entrained gases in the liquid. (28)(29)(30)(31)(32)(33) Some work indicates that contact resistance decreases with increasing Reynolds number (28,29) and also with time(30) until it disappears after prolonged operation, apparently as the liquid "cleans" the walls and/or is purified by trapping and separation. Other work indicates that precautions taken to ensure surface "cleanliness" and the absence of entrained gases will eliminate the contact resistance (32)(33)(34)(35) or reduce it to an insignificant value whether or not wetting is achieved.…”

Field Research of Firing Stored Peat Critical Conditions

“…Literature observation [6][7][8][9][10][11][12][13][14][15] showed that peat inflammability problem naturally and while stored is an important but understudied issue. It is possible that this might be the reason which stands on a way of practical time effective peat fire prevention and firefighting problem solution.…”
