▪ Abstract As a molten alloy or any multi-component liquid is cooled and solidified the
growing solid phase usually forms a porous matrix through which the residual liquid can …

Overwhelming research interest in developing green and renewable energy systems has
fostered the innovation of novel latent heat storage systems. Transport phenomena during …

The main purpose of this chapter is to give a derivation, which is mathematically precise,
physically natural, and conceptually simple, of the quasilinear system of partial differential …

This book presents an account of theories of? ow in porous media which have proved
tractable to analysis and computation. In particular, the t-ories of Darcy, Brinkman, and …

Finding consistent, analytical discussions of processes and principles of lyophilization can
be challenging and often frustrating. The first resource to gather information about the field …

The macro-scale segregation of alloying elements during the casting continues to afflict the
manufacturers of steel ingots, despite many decades of research into its prediction and …

The formation of macrosegregation and freckles by multicomponent thermosolutal
convection during the directional solidification of single-crystal Ni-base superalloys is …

A Rayleigh number based criterion is developed for predicting the formation of freckles in Ni-
base superalloy castings. This criterion relies on finding the maximum local Rayleigh …

Channel segregation–known as freckle–is one of the most complex defects which severely
limit mechanical properties of investment cast single-crystal turbine blades. The freckle …

We describe a series of laboratory experiments in which aqueous salt solutions were cooled
and solidified from above. These solutions serve as model systems of metallic castings …
