modelHeatTransferBaseClass
Base class for heat transfer correlation in terms of Nusselt number
Information
This is a base class for a heat transfer model usable for inner and outer heat transfer. It is located between a vector of thermal ports on the other hand and on a (vector of) fluid flow(s) on the other hand. In a derived class you have to specify
- Nusselt numbers Nu[numberOfNodes] OR heat transfer coefficients alpha[numberOfNodes] for each thermal port
- heatingSurfaceFactor (factor for A_h because of fins or s.th.)
- Psi (factor for ACrossFlow because of internals)
- fluid temperatures (input T[ns])
- fluid states [ns]
- fluid mass flow rates [ns]
As a result, you can use the heat flow rate Q_flow[numberOfNodes], which leaves the fluid, and the thermalPort.Q_flow[numberOfNodes], which enters the fluid ports. The difference is due to the heatloss to ambient.
