Highlight

A numerical model has been implemented with the aim of giving quantitative outcomes in addition to qualitative information. The major role of the convection patterns on the carbon flux is demonstrated. A good agreement between computed and experimental growth rates is obtained as a function of temperature, making simulation an adapted predictive tool for the further development of the process.
