“…Currently, the simulation works related to droplet deposition and fusion processes are mainly based on 2D models, which focus on the normal impinging of single droplet onto a fixed substrate surface [12][13][14][15][16][17][18][19][20][21]. However, 2D models could not provide comprehensive details of the deposition process.…”

Abstract. Successive deposition of uniform metal droplet is a new kind of 3D printing and rapid prototyping (RP) technology. Broad interests have been aroused in the deposition of metal droplets due to its potential application in microstructures fabrication. In this paper, the 3D models based on a volume of fluid (VOF) method were developed to investigate the successive deposition of molten metal droplets on a horizontally moving aluminum substrate surface and manufactured the typical thin-walled parts using the process of metal droplet deposition. The impinging, spreading and fusion processes of droplets were investigated under uniform substrate velocities. The simulated final morphology of droplets agreed well with experiments carried out under the same conditions. It was found that the molten metal droplets solidified in a layer by layer from the outer to the inner due to the high heat conductivity. A series of arc-shaped ridges appeared on the surface of solidified droplets, which resulted from the integrated effects from solidification and fusion consisting of alternately spreading and fusion of droplets. The works should be helpful for the process optimization and non-destructive detection of drop-based rapid prototyping techniques.

“…Heating, evaporation and ignition of liquid condensed substances drops at contact with hot plate are strongly investigated [1][2][3][4][5][6]. Such interest can be explained by absence of information about main regularities of interconnected heat and mass transfer processes.…”

Abstract.A numerical investigation of heat and mass transfer processes at the heating of combustible liquid was carried out at the interaction of hot small-size steel particle with gasoline. Developed mathematical model considers at two-dimensional statement thermal conduction, thermal convection, transfer of energy by phase change (evaporation of liquid fuel and crystallization of particle material), partial immersion of hot particle in liquid fuel, forming of vapor gap between hot particle and liquid fuel, diffusion of fuel vapors in oxidizer, dependence of thermophysical characteristics of interactive substances on temperature. It was established that the highest rates of heat and mass transfer processes in a system "hot particle -gasoline -air" are possible at temperature of hot particle higher than melting temperature of it material due to the additional heat released at the crystallization of material.

“…The authors found the relation between the dynamics of vapor bubble during condensation and intensity of heat exchange at vapor bubble interface. Bubble dynamics of vapor bubbles in subcooled liquids have been investigated (both experimentally and numerically) by researchers [2][3][4][5][6][7][8][9]. Numerical investigations using volume of fluid (VOF) method have been recently carried out by Ganguli [2].…”
