Single component flash / simulations

[andr1976]

Is there an easy way to work with single component simulations being in a saturated state, e.g. specifying a fluid or a stream with given pressure and vapor fraction? Does anyone have success running dynamic simulation with saturated single component fluids?

Hi!

• Does anyone have success running dynamic simulation with saturated single component fluids?
  See (still some work to be done):

• Stream with given pressure and vapor fraction
  See colab notebook and following code;

fluid2 = fluid('srk')
fluid2.addComponent('propane', 1.0)
fluid2.setTemperature(-20.0, 'C')
fluid2.setPressure(10.0, 'bara')



flash = jneqsim.thermodynamicoperations.ThermodynamicOperations(fluid2)
flash.constantPhaseFractionPressureFlash(0.5)
flash.constantPhaseFractionTemperatureFlash(0.5)

To specifiy the gas fraction at give pressure (and calculate temperature):

stream1 =  stream('feed stream', fluid1)
stream1.setSpecification('gas quality')
stream1.setPressure(10.0, 'bara')
stream1.setGasQuality(0.5)
stream1.setFlowRate(1000.0, 'kg/hr')
stream1.run()
