ADSimpleTurbine1PhaseUserObject

Computes and caches flux and residual vectors for a 1-phase turbine

A turbine is a parallel channel junction, a ADJunctionParallelChannels1PhaseUserObject, a type of volume junction, a ADVolumeJunction1PhaseUserObject. As such its base contribution to the residual and Jacobian is set by these classes.

The additional residual for the momentum equation in each direction are:

where is the pressure drop across the turbine, as computed below, the flow area and the direction of the turbine.

where is the inlet pressure, is the inlet conserved momentum variable, is the inlet enthalpy and is the ratio of the specific isobaric and isochoric heat capacities of the fluid.

For the energy equation, the residual is simply the work the turbine:
