Thermonator (Thermodynamics calculator)

Main features:

- Calculate states, processes and cycles of free-designed systems or theoretical proposals.

- Educational hints: Quick remainders of thermodynamic concepts and formulas.

- Interactive graph (Pressure-Volume, Temperature-Entropy, Enthalpy-Entropy, etc) with linear or logarithmic scales, automatic zoom, and interactive rulers.

- State properties: Pressure, Temperature, Volume, Internal energy, Enthalpy, Entropy, Exergy, Specific heat (isobaric and isochoric), Vapor quality, Saturated properties.

- Process properties: Heat, Work, Expansion work, Technical work, Flux work, and increments of main state properties.

- Cycle properties: Thermal efficiency, COP heating, COP cooling, plus all the process properties.

- Automatic calculation of cycles: Carnot, Otto, Diesel, Dual-Mixed, Stirling, Joule-Brayton, Regenerative heat exchanger*, Power Rankine*, Refrigeration Rankine*, Rankine plus open or close heat exchangers*.

- Configuration of the thermodynamic system as Control Mass or Control Volume (Closed system or Open system), and of the Sign Convention of the First Principle (∆U = Q - W, or ∆U = Q + W), to calculate the Work of the processes according your requirements.

- Customizable Dead State for exergy calculation, and Reference State for matching the results with any bibliography.

- Units: Pressure (bar, at, atm, kPa, MPa, psia), Temperature (K, C, R, F), Volume (m3, ltr, ft3, gal), Mass (mol, kmol, kg, lbm), Energy (J, kJ, kc, kWh, BTu), Power (W, kW, hp, hp(UK), BTus, BTUh).

- Substances: Water, Air, Ammonia, Carbon dioxide, Nitrogen, Oxygen, Alkanes (Butane, Ethane, Heptane, Hexane, Isopentane, Methane, Octane, Pentane, Propane), Alkenes (Ethylene, Propylene), Refrigerants* (R11, R12, R13, R14, R22, R23, R114, R123, R134A, RC318, R500, R502, Propyl alcohol), Ideal gases (Air, Water, Ammonia, Carbon monoxide, Carbon dioxide, Methane, Acetylene, Ethylene, Hydrogen, Nitrogen, Nitrogen monoxide, Oxygen, Hydroxide, Chlorine, Fluorine, Hydrobromic acid, Hydrogen chloride, Hydrogen iodide, Hydrogen sulfide, Sulfur dioxide) and Noble gases (Helium, Neon, Argon, Krypton, Xenon, Radon).

- Error detection and correction: Calculations are accurate, but software bugs are unpredictable. If you find an error, go to the "Send feedback" menu and explain me how to reproduce it, so I can fix it. You will receive a free license with all the extra features for your collaboration.

- Extra features: You can buy-in extra features (marked with *) for advanced calculations.
