.AixLib.Fluid.MixingVolumes.Validation.MoistureMixingConservationDynamicBalance

Information

This model verifies if mass and energy are conserved, using a dynamic balance. Two air streams with different mass flow rate are humidified by a mixing volume with two different vapor mass flow rates. These flows are then mixed. Boundary integrals are used to verify if air mass, vapour mass and internal energy are conserved.

Note, however, that there is some approximation error because in its default configuration, the conservation balance models simplify the treatment of the water that is added to the fluid. See AixLib.Fluid.Interfaces.StaticTwoPortConservationEquation and AixLib.Fluid.Interfaces.StaticTwoPortConservationEquation for a discussion.
