Abstract |
This thesis implicates the use of Phase-field method, to create a simulation of the transient thermal of the surface of a metallic material, molten or solidified by the heat flux during process. The project itself is considered acquainted with mass conservation equation, momentum equation, energy equation and level-set equation. In order to reach the results within the flow field domain, temperature, pressure, streamline and level-set number. This research is about the changes of corner flow between fusion area and solid area, uses different boundary conditions to forecast the disparity of corner field change. Such as solidified, surface fill, whirlpool phenomenons or the formation of ripples. In add, the results will display the area where flows of the molten are forced by thermocapillary. Which is caused by surface tension and temperature gradient. |
