# Information

Two main base class are defined:

- PartialHeatTransfer
- PartialHeatTransfer_IdealFluid

# PartialHeatTransfer

The Partial model **PartialHeatTransfer** is the basic model for heat transfer of a real fluid in the library. It calculates the

heat flux, q_dot[n], exchanged through the thermal port, ThermalPortL[n], for each segment n, based on the thermodynamic state of the fluid flow ,FluidState[n], and the temperatures at the boundary, T_fluid and thermalPortL.T.

In order to complete the model – from partial model to model – one equation relating the exchanged heat flux, q_dot, with the fluid temperature, T_fluid, and the temperature at the boundary thermalPortL.T has to be provided.

# PartialHeatTransfer_IdealFluid

The Partial model **PartialHeatTransfer_IdealFluid** is the basic model for heat transfer of an ideal fluid in the library. It calculates the heat flux, q_dot, exchanged through the thermal port, ThermalPortL. In order to complete the model – from partial model to model – one equation relating the exchanged heat flux, q_dot, with the fluid temperature, T_fluid, and the temperature at the boundary thermalPortL.T has to be provided
