Information

A HeatConductionTT model with N=5 nodes is shown above, in the same manner a larger model can be created. In the model, at each heat capacitor, a capacitance is defined which varies according to the mass. Moreover, between each heat capacitor a thermal conductor is placed which transports the heat without storing it.

For the each thermal conductor element, the conductance for a box geometry under the assumption that the heat flows along the box length is calculated as follows: G = lambda * A / (L / (N - 1)). Heat capacity of the heat capacitors is calculated as follows: C = cp * m / (N - 2)

The parameters for HeatConductionTT_Modelica are:

Parameters	Comment
L	length of the rod
N	number of nodes
cp	material specific heat capacity
rho	material density
A	cross section area of the rod
m	mass of the rod
v	volume of the rod
lambda	material thermal conductivity
T0	Initial temperature of the heat capacitors
T1	fixed temperature at the first node
TN	fixed temperature at the last node
