Numerical study of melt pool dynamics and bubble behavior in the laser powder bed fusion remelting process by Shengliang Luo, Guang Fu, Zhihao Ren, Hang You, Zhengwen Zhang

“…The molten flow within the melt pool is influenced by both Marangoni convection and the spatial distribution of vapor recoil pressure. During the LPBF process, bubbles formed within the melt pool move synchronously with the molten liquid, and some bubbles coalesce during their migration, eventually becoming trapped as pores within the solidified layer. …”

Computer Modeling in the Application to Geothermal Engineering by Karpenko Vasily Nikolaevich, Yuriy Starodub, Andrii Havrys

“…The novelty of the obtained research results: (i) developed the mathematical model of the physical process of origin and distribution in the bowels of the density of geothermal energy of the Earth from the surface to its center, which is the density of internal energy of an elementary geological object, and which increases when approaching the center of the planet; (ii) developed the mathematical model of the thermal energy source of infrared (IR) waves of the elementary geophysical object of the Earth’s interior depending on the depth of its occurrence, which allows to determine the stable generation of geothermal energy by rocks in a deep well for extraction and conversion into electricity and to study the geological structure and physical properties of the Earth’s interior; (iii) the mathematical model of heat exchange between the layers of the Earth’s subsoil with the thermal energy of infrared waves according to the laws of Fourier thermal conductivity and Stefan–Boltzmann heat transfer, which together with the geothermal energy source model allows to determine a thermal capacity of rocks in a deep well; (iv) developed the mathematical model of stable action of a source of thermal energy in the center of mass of the Earth, in the absence of which it is hard to explain the power of its endogenous infrared heat flux, parameters of geothermal energy distribution in the Earth, and the current thermodynamic state of the atmosphere, and the change in temperature of which depends on the thermophysical parameters of the physical-chemical composition of the atmosphere more than on changes in the thermal activity of the Sun; (v) determination of new numerical values: thermophysical parameters of the Earth’s interior; kinetic, potential and own gravitational energy of the Earth and own gravitational energy of the planets of the Solar System.…”
