Underground coal gasification (UCG) has received renewed interest due to its potential for utilization of the vast amounts of coals available in deep underground seams and the current drive towards clean coal utilization. UCG process involves the reaction between air/steam and coal in ... Read More

Homogeneous Heating of Milk

A. Stahel, and A. Reichmuth
Berner Fachhochschule
Biel, Switzerland

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. The goal is quickly to achive a uniform temperature of 37°C, without ever exceeding 40°C. Using COMSOL Multiphysics and a measurement ... Read More
