EngineeringFluids

Fast, unit-typed thermodynamic and transport properties for engineering fluids in .NET.

Built on EngineeringUnits.Fast: every input and output is a typed quantity (Pressure, Temperature, Enthalpy, ...), so there are no unit mix-ups and no conversions by hand.

Currently supports Ammonia (R717) using the Gao et al. (2020) Helmholtz equation of state, with results that match CoolProp / SharpFluids.

Install

dotnet add package EngineeringFluids

Quick start

using EngineeringFluids.Fluids;
using EngineeringUnits.Fast;

var nh3 = new Ammonia();

// Single-phase state from pressure and temperature
nh3.UpdatePT(Pressure.FromBar(10), Temperature.FromDegreeCelsius(50));

Console.WriteLine(nh3.Density.KilogramPerCubicMeter);
Console.WriteLine(nh3.Enthalpy.JoulePerKilogram);
Console.WriteLine(nh3.Cp.JoulePerKilogramKelvin);
Console.WriteLine(nh3.DynamicViscosity.PascalSecond);
Console.WriteLine(nh3.Phase);

// Two-phase state from pressure and vapor quality (0 = saturated liquid, 1 = saturated vapor)
nh3.UpdatePX(Pressure.FromBar(5), 0.3);

Console.WriteLine(nh3.Temperature.DegreeCelsius);   // saturation temperature
Console.WriteLine(nh3.Quality);

State updates

Method Inputs
UpdatePT pressure, temperature (optionally a phase hint)
UpdatePH / UpdatePHExact pressure, enthalpy
UpdatePS / UpdatePSExact pressure, entropy
UpdatePX / UpdatePXExact pressure, vapor quality
UpdateTX / UpdateTXExact temperature, vapor quality
UpdateTS temperature, entropy
UpdateHS enthalpy, entropy
UpdateDT density, temperature
UpdateDP density, pressure
UpdateDH / UpdateDS density, enthalpy / entropy

The plain methods read the saturation dome from fast ancillary fits. The Exact variants solve the phase equilibrium against the equation of state instead: a bit slower, but they agree with CoolProp to about 1e-10 and work all the way up to the critical point. Use Exact when you need CoolProp-identical results.

Properties

Pressure, temperature, density, enthalpy, entropy, internal energy, Cp, Cv, speed of sound, viscosity, thermal conductivity, Prandtl number, surface tension, fugacity, compressibility, phase, quality, saturation temperature/pressure, critical and triple-point data, and validity limits.

All properties of a state are computed from a single cached equation-of-state evaluation, so reading many properties costs about the same as reading one. Once a state is set, it can be read from multiple threads at the same time.
