- Transient filling and emptying
Power, refrigeration and design
- Rankine, reheat, regenerative and combined cycles
- Otto, Diesel, Dual, Brayton and turbojet cycles
- Vapour-compression, heat-pump, gas, cascade and multistage refrigeration
- Liquefaction, endoreversible power, thermal-radiation exergy and entropy-generation minimisation
Moist air and reacting systems
- Psychrometric states, air-conditioning processes and cooling towers
- Combustion stoichiometry, product analysis and reacting energy balances
- Adiabatic and equilibrium flame temperatures
- Chemical exergy, fuel cells, chemical equilibrium and constant-volume combustion
BUILT FOR EXPLORATION
Use sliders where a meaningful exploration range is available. Results and diagrams update as inputs change. Every calculator shows its governing relation, units, assumptions and model limits.
TAKE THE RESULT WITH YOU
Export readings as CSV, copy tab-separated values into a spreadsheet, and export supported plots for reports or coursework.
OFFLINE AND PRIVATE
The calculations and both manuals are included in the app. No account is required. ThermalOne makes no network requests and collects no data.
Requires iPadOS 17 or macOS 14.
