When milk is taken out of a refrigerator it has to be heated up to 37°C. The standard solution is to put the bottle in a bath of warm water and wait. ...

High Temperature Process Simulation

O. Geoffroy, and H. Rouch
INOPRO, Villard de Lans, France

The crystal growth industry uses high temperature processes. To improve production efficiency, a good knowledge of thermal effects is necessary. We show in this article a methodology to get reliable data by mixing simplified models, sensitivity studies and parameters adjustments. The precision is improved by comparison with experimental measurements.
