| Popis: | 106 In this study, the shape of molten pool is irradiated by the energy flux of Gaussian distribution, for different surface active element sulfur and beam intensities is discussed. A keyhole can be produced by a concentrated the energy flux. The model proposed including two-dimensional transient, phase-field method, mass conservation equation, momentum equation, energy equation and phase-field function. Finally, the computer result the effect of thermocapillary force on the flow behavior in the molten region and the development of keyhole. |
