Direct numerical simulation of an iron rain in the magma ocean
[1] Core formation in terrestrial planets is a complex process, possibly involving several mechanisms. This paper presents a direct numerical simulation of one of these, the separation of an emulsion of metal in a magma ocean. The model, using a fully Lagrangian approach called the moving particle semi-implicit method, solves the equations of fluid dynamics, including a proper treatment of surf...
متن کاملThermal Simulation of a Magma Ocean on Asteroid 4 Vesta
Introduction: Recent work on chronology seem to point to older ages for eucrites: which favor a magma ocean model for Vesta. [1] indicate a Pb-Pb age for the eucrite Asuka 881394 of 4.566 + 0.3 Ga. Whole rock isochrons of eucrites based on Hf-W, Al-Mg and Mn-Cr [2-4] indicate somewhat younger ages at around 4.564 Ga (or about 3.5 Myrs after CAI formation). From the perspective of thermal modeli...

Absolute Permeability Calculation by Direct Numerical Simulation in Porous Media
Simulating fluid flow at micro level is an ongoing problem. Simplified macroscopic flow models like Darcy’s law is unable to estimate fluid dynamic properties of porous media. The digital sample reconstruction by high resolution X-ray computed tomography scanning and fluid-dynamics simulation, together with the increasing power of super-computers, allow to carry out pore-scale simulations throu...
متن کاملNumerical Simulation of Oil Spill in Ocean
The spreading of oil in an open ocean may cause serious damage to a marine environmental system. Thus, an accurate prediction of oil spill is very important to minimize coastal damage due to unexpected oil spill accident. The movement of oil may be represented with a numerical model that solves an advection-diffusion-reaction equation with a proper numerical scheme. In this study, the spilled o...
