Computer Simulation of Equidxed Eutectic Solidifiction of Metals
In the present work, the solidification process was simulated in both macroscopic and microscopic scales. Two-dimensional heat transfer equation for conduction was applied for macroscopic modeling using enthalpy formulation and finite element method. In order to decrease execution time and/or memory capacity in finite analysis, skyline mathematical technique was adapted. The microenthalpy metho...
متن کاملElectrochemical properties of iron oxide nanoparticles as an anode for Li-ion batteries
The synthesis of iron oxide nano-particles by direct thermal decomposition was studied. Simultaneous thermal analysis and Fourier transform infrared spectroscopy results confirmed the formation of iron-urea complex, and disclosed iron oxide formation mechanism. Calcination of the iron-urea complex at 200°C and 250°C for 2 hrs. resulted in the formation of maghemite along with hematite as a seco...
متن کاملDELFT UNIVERSITY OF TECHNOLOGY REPORT 08-05 Theoretical Comparison of Two-Level Preconditioners based on Multigrid and Deflation
It is well-known that two-level preconditioned conjugate gradient (PCG) methods provide efficient techniques for solving large and sparse linear systems whose coefficient matrices are symmetric and positive definite (SPD). A two-level PCG method combines traditional and projectiontype preconditioners to get rid of the effect of both small and large eigenvalues of the coefficient matrix. In the ...

متن کاملModeling of Unsteady-State Cake Formation on a Fracture in Produced Water Re-Injection Process (PWRI)
In petroleum production, Produced Water Re-Injection (PWRI) has earned much interest among disposal methods of the produced water. However, presence of the contaminants in the produced waters usually results in formation damage in well bores and their surrounding fracture systems. In the present study, modeling of external cake formation on a fracture in unsteady-state conditions i...
