We have answers! Here are some of the most common questions we hear from engineers and companies evaluating Arrow. Topics include sonic choking, liquid vs. gas applications, real-gas effects, model size limits, turbine and relief valve modeling, loss calculations, and gas mixtures.
Yes, Arrow accurately models sonic choking at all three geometric conditions in compressible networks.
No—Arrow is for gas/steam systems; it’s built on a gas equation of state. It can, however, model incompressible gas flow found in vents and many HVAC applications.
Real-gas behavior is handled via a compressibility factor from an equation of state or property database, and heat transfer is modeled along pipes/ducts, across heat exchangers, and in compressors/fans with energy balances at junctions.
Arrow supports up to 10,000 pipes and 10,000 junctions; before that, RAM typically becomes the constraint, roughly 32 × (branches + tees)² bytes are needed (e.g., ~32 MB for 1,000 branches/tees).
Not directly; model it with a Heat Exchanger junction by entering the turbine’s pressure drop vs. flow and specifying a heat rate out to capture both the pressure drop and enthalpy reduction.
It uses Idelchik-based correlations that account for flow split, area changes, and branch angles to compute pressure losses accurately.
Use a Relief Valve junction (normally closed; Arrow opens it when cracking pressure is reached) or a regular Valve if you know it’s open; for choked-flow checks through valves/orifices, enter CdA on the junction’s Optional tab.
Create mixtures using NIST REFPROP or the optional Chempak database (the Standard database doesn’t mix); assign gases/mixtures to sources and Arrow carries composition through the network via species mass conservation.
