A stabilized volume-averaging finite element method for flow in porous media and binary alloy solidification processes
Nicholas Zabaras,Deep Samanta +1 more
TL;DR: In this paper, a stabilized equal-order velocity-pressure finite element algorithm is presented for the analysis of flow in porous media and in the solidification of binary alloys, where the adopted governing macroscopic conservation equations of momentum, energy and species transport are derived from their microscopic counterparts using the volume-averaging method.
Control of macrosegregation during the solidification of alloys using magnetic fields
Deep Samanta,Nicholas Zabaras +1 more
TL;DR: In this paper, a finite-dimensional optimization problem based on the continuum sensitivity method is considered to design the time history of the imposed magnetic field required to effectively damp convection, and the coefficients that determine this time variation are the main design parameters of this optimization problem.

Numerical study of macrosegregation in Aluminum alloys solidifying on uneven surfaces
Deep Samanta,Nicholas Zabaras +1 more
TL;DR: In this paper, the effect of changing surface topography on fluid flow, macrosegregation and inverse segregation in the solidifying alloy is studied. But the authors focus on the vertical solidification of aluminum alloys and do not consider the horizontal solidification.

Modelling convection in solidification processes using stabilized finite element techniques
Deep Samanta,Nicholas Zabaras +1 more
TL;DR: In this paper, a single domain model is considered with a fixed numerical grid and without boundary conditions applied explicitly on the freezing front, where the mushy zone is modelled as a porous medium with either an isotropic or an anisotropic permeability.
A coupled thermomechanical, thermal transport and segregation analysis of the solidification of aluminum alloys on molds of uneven topographies
Deep Samanta,Nicholas Zabaras +1 more
TL;DR: In this paper, a coupled thermomechanical, thermal transport and segregation analysis of aluminum alloys solidifying on uneven surfaces is presented, where sinusoid surfaces are modelled as sinusoids with different wavelengths and amplitudes and the role of inverse segregation, arising from shrinkage driven flow in the melt, melt superheat and varying mold surface topography on nucleation of air-gaps and evolution of stresses in the solidifying shell is examined.
