java.lang.Enum<PipeBeggsAndBrills.HeatTransferMode>

neqsim.process.equipment.pipeline.PipeBeggsAndBrills.HeatTransferMode

All Implemented Interfaces:

Serializable, Comparable<PipeBeggsAndBrills.HeatTransferMode>, Constable

Enclosing class:

PipeBeggsAndBrills

public static enum PipeBeggsAndBrills.HeatTransferMode
extends Enum<PipeBeggsAndBrills.HeatTransferMode>

Heat transfer calculation modes for pipeline thermal modeling.

Controls how temperature changes along the pipeline are calculated:

• ADIABATIC: No heat transfer (Q=0), temperature changes only due to Joule-Thomson effect
• ISOTHERMAL: Constant temperature along the pipe (outlet T = inlet T)
• SPECIFIED_U: Use a user-specified overall heat transfer coefficient (U-value)
• ESTIMATED_INNER_H: Calculate inner h from flow (Gnielinski correlation), use as U
• DETAILED_U: Calculate inner h from flow, then compute overall U including pipe wall, insulation, and outer convection resistances
