Improved sol based ceramic moulds for use in investment casting
… techniques. The mould structure is shown to be nonuniform and unpredictable, with poor packing of the ceramic constituents leading to a non-uniform porosity network. The structure and distribution of the binder is also established and this indicates that the major load bearing points within the …

Numerical multiphysics modelling of Wick-Boiling in a crud with porosity variations to determine local Nickel Ferrite depositions within crud due to deep bed filtration
Impacts of porosity variations through porous deposits with chimneys where wick boiling contributes to bulk of heat transfer, on thermal performance, solute concentration levels and particle number density distribution are examined through a two-dimensional model. The multi-physics model is …

The nanostructure and degradation of C-S-H in Portland and blended cements
… systems cured at higher temperature exhibited non uniform porosity. Inner product C-S-H with a fine scale, homogeneous morphology, was abundant in all systems cured at 55'C and 85'C. Op C-S-H was generally fibrillar with Nvater, and foil-like with alkali. However, the higher temperature curing …
