“…The review of recent studies on the influence of micro/nanomodifiedsurfaces and coatings on heat transfer enhancement and critical heat flux increase at boiling is presented in [2]. There are another techniques for heated surfaces such as spray cooling, systems based on evaporation of a thin liquid layer or rivulet [3,4], thermoelectric coolers. Dynamics of evaporation depends on the conditions in the layer [5].…”

Abstract. The boiling heat transfer on the local heaters with microstructured and nanomodified surfaces was studied. As nanomodified surfaces we used copper ones where the microropes of silicon oxide nanowires were grown. The aging of the nanomodified surface was observed after first series of experiments. It was shown that both finning and nanostructuring of the surface result in increase of heat transfer. The heat flux density of 1400 W/cm 2 was reached.

“…Heat transfer in an evaporating droplet on the horizontal heated foil and in a water rivulet flowing down over the vertical heated foil was studied in [6,7]. The fluctuating temperature measurements made by the IR-scanner were used to solve the Cauchy problem and to measure heat flux density on the surface with the droplet and on the surface with the rivulet.…”

Abstract. Heat transfer at rivulet FC-72 flow over the constantan vertical heated foil with the length of 80 mm, width of 35 mm, and thickness of 25 mm was studied experimentally. Distributions of temperature on the bottom side of foil from the rivulet flow using the infrared thermographic data were obtained. In the future heat flux from the foil will be calculated with help of Koshi problem solution. It was shown that the rivulet width as the liquid flow rate increases, and it narrows as heat power increases due to the high evaporation rate. In the case with water, the rivulet narrows not so intensively as compared with the rivulet of FC-72 liquid. Good wettability and low heat of vaporization of FC-72 liquid contribute to using it to develop effective cooling systems.

“…According to analysis, the structure of two-phase flow is mainly influenced by the following parameters: channel geometry and dimensions, parameters of the inlet section and liquid properties such as viscosity and surface tension. In [7][8][9], the influence of the inlet section on the two-phase flow structure is analyzed, and it is shown that the conditions of gas and liquid input affect substantially the borders of two-phase flows in microchannels. The flows in the rectangular channels of various heights and widths are compared in [10][11][12].…”
