Measuring the rate of local evaporation from the liquid surface under the action of gas flow

Experimental determination of change in the liquid layer thickness on the heated surface by confocal sensor

“…In this case, one of the most effective ways of removing heat from the heatloaded elements is the use of cooling systems based on evaporation of thin liquid layers [12,13]. Compared to traditional systems, such systems use high energy potential of the phase transition [8,9,12,14]. Due to this effect, high intensity of heat removal during evaporation of thin liquid layers provides keeping of the required temperature mode of the element.…”

“…So to remove high heat flows around 1000 W/cm2 [9][10][11], it is necessary to use enhanced heat exchange surfaces exceeding the area of heat source. In this case, one of the most effective ways of removing heat from the heatloaded elements is the use of cooling systems based on evaporation of thin liquid layers [12,13]. Compared to traditional systems, such systems use high energy potential of the phase transition [8,9,12,14].…”

Convection flow study within a horizontal fluid layer under the action of gas flow

“…The processes of convection, accompanied by evaporation at the interface, are actively studied experimentally [1][2][3][4], numerically [4][5][6] and theoretically in the present time [6][7][8]. Scientific activity in this direction is determined by the experiments in the frame of the CIMEX project of the European Space Agency, [9].…”

Ignition Parameters of Diesel Layers Under Conditions of Local Heating

“…Methods for developed determination of ignition delay time the fluids in the fall of a fuel drop on a heated surface [10,11] for such of the ignition mode. Now also accumulated extensive information about heat and mass transfer during evaporation of pure liquids from the surfaces of the heating [12,13]. But these models [6][7][8][9][10][11][12][13] did not explain how ignition characteristics depend on layer thickness.…”

“…Now also accumulated extensive information about heat and mass transfer during evaporation of pure liquids from the surfaces of the heating [12,13]. But these models [6][7][8][9][10][11][12][13] did not explain how ignition characteristics depend on layer thickness. However, the impact of subsurface layer heterogeneity on integral characteristics of ignition was presented in studies [14,15], where structurally inhomogeneous condensed matters were considered.…”
