i am trying to make interphase mass transfer achieve a decomposition reaction.
1.set up reaction: REACTION: Reaction 1 Option = Single Step COMBUSTION MODEL: Chemical Timescale = 1.37E-4 [s] Option = Finite Rate Chemistry END FORWARD REACTION RATE: Option = Expression Reaction Rate = HydrateRate END PRODUCTS: Materials List = CH4,Water Option = Child Materials CHILD MATERIAL: CH4 Option = Stoichiometric Stoichiometric Coefficient = 1.0 END CHILD MATERIAL: Water Option = Stoichiometric Stoichiometric Coefficient = 6 END END REACTANTS: Materials List = hydrate Option = Child Materials CHILD MATERIAL: hydrate Option = Stoichiometric Stoichiometric Coefficient = 1.0 END END END END 2.set up reaction energy: BULK SOURCES: Option = Use Volume Fraction EQUATION SOURCE: energy Multiply by Porosity = Off Option = Source Source = HeatSource END END 3.set up interphase mass transfer: FLUID PAIR: Gas | Hydrate INTERPHASE HEAT TRANSFER: Heat Transfer Coefficient = 5 [W m^-2 K^-1] Option = Heat Transfer Coefficient END INTERPHASE TRANSFER MODEL: Option = Particle Model END MASS TRANSFER: Option = Specified Mass Transfer SPECIFIED MASS TRANSFER: Fluid1to2 Mass Flux = GasMassFlow Option = Interfacial Mass Flux END END MOMENTUM TRANSFER: DRAG FORCE: Drag Coefficient = 4 Option = Drag Coefficient END LIFT FORCE: Option = None END VIRTUAL MASS FORCE: Option = None END WALL LUBRICATION FORCE: Lubrication Coefficient C1 = -0.01 Lubrication Coefficient C2 = 0.05 Option = Antal END END END FLUID PAIR: Gas | Water INTERPHASE HEAT TRANSFER: Heat Transfer Coefficient = 0.6 [W m^-2 K^-1] Option = Heat Transfer Coefficient END INTERPHASE TRANSFER MODEL: Interface Length Scale = 1. [mm] Option = Mixture Model END MASS TRANSFER: Option = None END MOMENTUM TRANSFER: DRAG FORCE: Drag Coefficient = 4 Option = Drag Coefficient END END END FLUID PAIR: Hydrate | Water INTERPHASE HEAT TRANSFER: Heat Transfer Coefficient = 50 [W m^-2 K^-1] Option = Heat Transfer Coefficient END INTERPHASE TRANSFER MODEL: Option = Particle Model END MASS TRANSFER: Option = Specified Mass Transfer SPECIFIED MASS TRANSFER: Fluid1to2 Mass Flux = WaterMassFlow Option = Interfacial Mass Flux END END MOMENTUM TRANSFER: DRAG FORCE: Drag Coefficient = 4 Option = Drag Coefficient END LIFT FORCE: Option = None END VIRTUAL MASS FORCE: Option = None END WALL LUBRICATION FORCE: Option = None END END END 4.error: ERROR #001100279 has occurred in subroutine ErrAction. Message: Floating point exception: Multiple faults | ERROR #001100279 has occurred in subroutine ErrAction. | Message: | Stopped in routine FPX: C_FPX_HANDLER Thanks for anyone who gives me a view. |
