Shape and stability of doubly connected axisymmetric free surfaces in a cylindrical container

- L. Slobozhanin, J. Alexander, A. Fedoseyev
- Physics
- 4 November 1999

The equilibrium and stability of a liquid that partially fills a cylindrical container with planar ends are examined. It is assumed that the free surface is axisymmetric and does not cross the… Expand

Investigation of vibrational control of convective flows in Bridgman melt growth configurations

- A. Fedoseyev, J. Alexander
- Chemistry
- 1 April 2000

It is generally recognized that oscillatory, or pulsatile, flow significantly alters the transfer of mass, heat and momentum in fluid systems. A numerical investigation of thermovibrational… Expand

An Inverse Finite Element Method for Pure and Binary Solidification Problems

- A. Fedoseyev, J. Alexander
- Materials Science
- 15 January 1997

A 2D axisymmetric formulation for the solution of a directional solidification problem using an inverse finite-element method (IFEM) is presented. An algorithm developed by A. N. Alexandrou (Int. J.… Expand

A REGULARIZATION APPROACH TO SOLVING THE NAVIER-STOKES EQUATIONS FOR PROBLEMS WITH BOUNDARY LAYER

- A. Fedoseyev
- Mathematics
- 1999

We present an alternative method for treating numerically a problem of viscous flow with a boundary layer that is based upon regularization of the Navier-Stokes equations. Shishkin (1997) showed that… Expand

One-dimensional unsteady fluid motion between two infinite walls

- R. Lemdiasov, V. Tenishev, A. Fedoseyev
- Physics
- 5 June 2002

We considered an incompressible fluid motion driven by space-dependent body force. For a one-dimensional case, the problem was solved analytically, with the arbitrary choice of body force coordinate… Expand

Minimizing segregation during the controlled directional solidification of dendritic alloys

- R. Grugel, A. Fedoseyev, Shinwoo Kim
- Materials Science
- 1 December 2002

Gravity-driven convection induced in the liquid by density gradients of temperature or composition disrupts uniform dendritic growth during controlled directional solidification and promotes severe… Expand

Characterizing the Use of Ultrasonic Energy in Promoting Uniform Composite Growth in Immiscible Alloys

- R. Grugel, A. Fedoseyev
- Materials Science
- 2000

The results of experimental investigation and mathematical modeling for immiscible alloys subjected to ultrasonic influence are presented. It is known that in inoculated light alloy melts, ultrasonic… Expand

Thermovibrational flow in Bridgman melt growth configurations

- A. Fedoseyev, J. Alexander
- Materials Science
- 11 January 1999

Characterizing the Use of Ultrasonic Energy in Promoting Uniform Microstructural Dispersions in Immiscible Mixtures

- R. Grugel, A. Fedoseyev, M. F. Rose
- Materials Science
- 2001

Gravity driven separation and preferential wetting precludes uniform microstructural distributions during solidification processing of immiscible, liquid-liquid mixtures. Historically, it is,… Expand

Space radiation effects in silicon solar cells: Physics based models, software, simulation and radiation effect mitigation

- A. Fedoseyev, S. Herasimenka
- Materials Science
- 24 October 2019

Improvements to solar cell efficiency and radiation hardness that are compatible with low cost, high volume manufacturing processes are critical for power generation applications in future long-term… Expand
