modelThermalConductor_Fluid
Extends from Modelica.Thermal.HeatTransfer.Components.ThermalConductor (Lumped thermal element transporting heat without storing it).
Information
1. Purpose of model
Modeling the thermal conduction between two fluid layers of same height. The model extends the models ThermalConductor from the Modelica Standard Library (MSL)
2. Level of detail, physical effects considered, and physical insight
Thermal conduction in fluid with constant specific heat condductivity considered.
3. Limits of validity
Thermal conduction in fluid with constant specific heat conductivity considered.
4. Interfaces
port_a: model gets temperature and gives the calculated heat flow back
port_b: model gets temperature and gives the calculated heat flow with changed sign back
5. Nomenclature
A_heat: Area of heat transfer
height_Seg: height of one fluid layer
k: Specific heat conductivity of fluid (0.6 means water)
6. Governing Equations
(no equations)
7. Remarks for Usage
