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

NameDescription
 MixerPHInlets: ports A and B. Outlet: port C. Uses mix enthalpy. Adequate for liquids and gases
 Mixer3PH
 Mixer4PH
 JunctionBidirectional mixer
 AbruptAdaptor
 PdiffSourceIntroduces a pressure loss between PortA and PortB. Is negative if PortB.P<PortA.P. If applicable, ports are isenthalpic.
 Dampener
 PipePhysicalPhysical description of a pipe of flexible shape, without fluid characteristics.
 PipePipe with two ports fluid ports and an internal fluid
 PipeFlowBaseBase model for a single medium pipe.
 PipeFlow1PhSingle pipe(not double) for single phase, full bore flow. With no detailed heat transfer model
 PipeFlowChokedSingle phase flow with detection of choked condition.
 PipeFlow2PhSingle pipe(not double) for two phases flow. With no detailed heat transfer model. Muller-Steinhagen and Heck method
 PipeThermalBaseBase model for pipes with thermal flow
 PipeForcedConvectionModel for pipes with thermal,single phase, flow
 PipeFallingFilmheat exchanged between a flowing fluid and the internal wall. It uses all the active pipe surface
 PipeCondensingBaseCondensation of pure vapors inside pipes. TwallC, TsurfC and Hc are those of condensation step
 PipeCondensing
 PipeCondSubcool
 CoilPhysicalGives pipes additional information regarding the coil shape
 CoilFlow1PhPower exchanged between a flowing fluid and the internal wall. Needs an external heat flow model. It uses all the active coil surface
 CoilForcedConvectionPower exchanged between a flowing fluid and the internal wall. Needs an external heat flow model. It uses all the active coil surface
 HalfCoilPhysical
 HalfCoilForcedConvectionsame as PipeThermalStd, but using as active heat transfer surface only de tank side
 HalfCoilCondensing
 PipeFluidBoundaryModels the external heat exchange against a fluid
