Information

1. Purpose of model

This model represents a generalized junction for real gases with n ports. It is a modified version of the model TransiEnt.Components.Gas.VolumesValvesFittings.RealGasJunction_L2. The model is documented there and here only the changes are described: The three ports were replaced by one vector, summary, eye and fluid models at port were deleted. Linear pressure losses can be turned on by setting Delta_p_nom to a value unequal to zero for the desired port. You can choose a quasi-stationary or dynamic mass balance implementations. Additionally, the parameter variableCompositionEntries can be used in case that not all components are freely variable, e.g. when hydrogen is fed into natural gas.
