Information

This is a 0 D package for fluid flow and heat transfer, with the calculation based in average properties.
It contains pipes and accesories, but not valves, that are in a separate package.

Contents

Name Description
 MixerPH Inlets: ports A and B. Outlet: port C. Uses mix enthalpy. Adequate for liquids and gases
 Mixer3PH
 Mixer4PH
 Junction Bidirectional mixer
 AbruptAdaptor
 PdiffSource Introduces a pressure loss between PortA and PortB. Is negative if PortB.P<PortA.P. If applicable, ports are isenthalpic.
 Dampener
 PipePhysical Physical description of a pipe of flexible shape, without fluid characteristics.
 Pipe Pipe with two ports fluid ports and an internal fluid
 PipeFlowBase Base model for a single medium pipe.
 PipeFlow1Ph Single pipe(not double) for single phase, full bore flow. With no detailed heat transfer model
 PipeFlowChoked Single phase flow with detection of choked condition.
 PipeFlow2Ph Single pipe(not double) for two phases flow. With no detailed heat transfer model. Muller-Steinhagen and Heck method
 PipeThermalBase Base model for pipes with thermal flow
 PipeForcedConvection Model for pipes with thermal,single phase, flow
 PipeFallingFilm heat exchanged between a flowing fluid and the internal wall. It uses all the active pipe surface
 PipeCondensingBase Condensation of pure vapors inside pipes. TwallC, TsurfC and Hc are those of condensation step
 PipeCondensing
 PipeCondSubcool
 CoilPhysical Gives pipes additional information regarding the coil shape
 CoilFlow1Ph Power exchanged between a flowing fluid and the internal wall. Needs an external heat flow model. It uses all the active coil surface
 CoilForcedConvection Power exchanged between a flowing fluid and the internal wall. Needs an external heat flow model. It uses all the active coil surface
 HalfCoilPhysical
 HalfCoilForcedConvection same as PipeThermalStd, but using as active heat transfer surface only de tank side
 HalfCoilCondensing
 PipeFluidBoundary Models the external heat exchange against a fluid
