modelSmoothed

Smoothed: Smooth transitions between the different zones

Extends from Greenhouses.Flows.FluidFlow.HeatTransfer.BaseClasses.PartialHeatTransferSmoothed (A partial heat transfer model that provides smooth transitions between the HTC for liquid, two-phase and vapour).

Information

The model Smoothed extends the partial model PartialHeatTransferSmoothed and calculates the heat transfer coefficient based on the following equation:

Note that in the model U_nom corresponds to the smoothed heat transfer coefficient calculated in PartialHeatTransferSmoothed
