TNA project : lines of descent

Acronym : 72-lines of descent-Giulio

Project Lead : Ottonello Giulio From : DISTAV-University of Genoa (Italy)

Dates : from 16th September 2013 to 20th September 2013

Description :



Motivation and objectives :
We are at present involved in a research aimed to solve the thermodynamic and numerical complexities of a precise location of equilibrium loci in high rank simplexes through polymer chemistry applications to multi-component melts coupled with convex-hull techniques. Visualization of the result is at present restricted to simplexes of rank 2 but we will soon have to afford the problem of a visualization for simplexes of higher rank.

Recordings & Results :
We are at present involved in a research aimed to solve the thermodynamic and numerical complexities of a precise location of equilibrium loci in high rank simplexes through polymer chemistry applications to multi-component melts coupled with convexhull techniques. Visualization of the result is at present restricted to simplexes of rank 2 but we will soon have to afford the problem of a visualization for simplexes of higher rank. Research questions : We think that the utilization of CAVE and of a stereoscopic immersive environment could allow a better appreciation of the intrinsically tridimensional topology of the cotectic surfaces delimiting the primary phase fields within a n=3 simplex (tetrahedral perspective). Basically the aim is the analysis of a predictive thermodynamic model based on few observable but generalized to the entire space of interest. In this context it extremely important the visualization of coherent (or aberrant) forms to address the research toward a more extensive experimental investigation or toward more detailed and satisfactory thermodynamic parameterization (model refinement). Once the paths of descent are correctly visualized, the code implementation to return the magnitudes of interest (to Material Science or Earth Sciences) will be almost ancillary because the topology is intimately linked to the magnitudes that are responsible of their nucleation and growth.

Conclusions :
The CMAS (CaO-MgOAl2O3- SiO2) system could be visualized and explored. Discussion on further steps are still going on.
