modelConstant

Constant: Constant heat transfer coefficient

Extends from Greenhouses.Flows.FluidFlow.HeatTransfer.BaseClasses.PartialHeatTransferZones (A partial heat transfer model with different HTC for liquid, two-phase and vapour).

Information

The model Constant compute a constant heat transfer coefficient as an average between the liquid the two-phase and the vapor term.
