package neqsim.process.safety.release
Source term generation for consequence modeling.

This package provides tools for calculating release source terms for QRA consequence analysis:

The source terms can be exported in formats compatible with consequence modeling tools:

  • PHAST (DNV)
  • FLACS (Gexcon)
  • KFX (DNV)
  • OpenFOAM

Example usage: 

SystemInterface gas = new SystemSrkEos(300.0, 50.0);
gas.addComponent("methane", 1.0);
gas.setMixingRule("classic");
gas.init(0);
gas.init(1);

LeakModel leak = LeakModel.builder().fluid(gas).holeDiameter(0.025) // 25mm hole
    .vesselVolume(10.0) // 10 m³
    .scenarioName("HP Separator Leak").build();

SourceTermResult result = leak.calculateSourceTerm(300.0, 1.0); // 5 minutes
System.out.println("Peak flow: " + result.getPeakMassFlowRate() + " kg/s");
System.out.println("Total released: " + result.getTotalMassReleased() + " kg");
