Solidification progress and heat transfer analysis of gas-atomized alloy droplets during spray forming
Eon-Sik Lee,S. Ahn +1 more
TL;DR: In this article, the authors used the Newtonian heat transfer formulation coupled with the classical heterogeneous nucleation and specific solidification process to predict gas and droplet velocities, droplet temperature, and fractional solidification with flight distance during spray forming, and found that the corresponding solid fractions formed during recalesced, segregated, and eutectic solidifications are linearly related to the degree of undercooling.

A fixed grid numerical modelling methodology for convection-diffusion mushy region phase-change problems
Vaughan R Voller,C. Prakash +1 more
TL;DR: In this article, an enthalpy formulation based fixed grid methodology is developed for the numerical solution of convection-diffusion controlled mushy region phase-change problems, where the basic feature of the proposed method lies in the representation of the latent heat of evolution, and of the flow in the solid-liquid mushy zone, by suitably chosen sources.

Free and moving boundary problems
TL;DR: In this paper, a front-tracking method is used to solve moving boundary problems and an analytical solution of seepage problems is proposed. But this method is not suitable for solving free boundary problems.
