The heat transfer by boiling in splits, capillaries, wick structures

Peculiarities of boiling heat transfer on capillary-porous coverings

“…While constructing the boiling model in ranges "b" and "c" with II-kind hysteresis, the authors relied on the work of Smirnov et al [14]. In that model, an elementary cell of a capillary-porous covering was substituted with a fragment of finned surface as presented in Fig.…”

“…On the basis of the condition that the sum of pressure drop in liquid and vapour jets moving in opposite directions should be smaller or equal to the capillary pressure increment, the boundary liquid micro-layer thickness δ l was calculated [14]:…”

Sintered Mesh Layers for the Production of Efficient Phase – Change Heat Exchangers

“…Fig. 3 presents the comparison of the experimental data for a meshed surface with selected correlations from literature, namely those developed by Smirnov et al [1,6,7], Nishikava et al [8] as well as Xin and Chao [9]. Performing calculations according to the model presented by Xin and Chao was possible after introducing certain modifications as for the geometrical parameters used in their formulae.…”

“…Smirnov et al [1] considered boiling of water and ethanol on a horizontally located heater that was covered with copper and brass meshes. These meshes were attached mechanically.…”

Distilled water and ethyl alcohol boiling heat transfer on selected meshed surfaces

“…The authors reported that for a given number of mesh layers there is an optimal aperture (distance between the wires) for which the maximal value of the critical heat flux is obtained. Smirnov et al [4] tested copper and brass meshes applied mechanically to the heaters. The working agents were water and ethanol.…”
