.FreeFluids.Pipes

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.

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
