modelConvHT2N
1D Convective heat transfer between two DHT connectors with a different number of nodes
Extends from Icons.HeatFlow, Modelica.Icons.ObsoleteModel (Icon for classes that are obsolete and will be removed in later versions).
Information
Model of a simple convective heat transfer mechanism between two 1D objects having (possibly) different nodes, with a constant heat transfer coefficient.
The heat flux through each node of side with a larger number of nodes is computed as a function of the difference between the node temperatures and the corresponding temperatures on the other side, obtained by linear interpolation.
The corresponding heat flux on the side with fewer nodes is computed so that the averaged heat flux around those nodes is equal to the averaged heat flux on the corresponding intervals on the other side.
