  4. 7. Thermal System Analysis : heat transfer in glass forming and fluid temperature-control systems

    Author : Karl Storck; Rolf Karlsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Thermal system analyses are often required, and conducted, in engineering problems in almost all engineering disciplines. The methods employed vary a great deal and must be specially adapted for each situation. Basically, two different methods are used, namely distributed modelling and lumped parameter modelling.
