Phase changes have been added to the game system and most gases now have an associated Liquid and a pure solid phase.
The following exist only in solid state and have no gaseous form: Charcoal, Coal, Silicon, Iron, Copper, Nickel, Silver, Gold, Lead, Uranium.
Mixtures
| Name | Contents | Tank Color | Notes |
|---|---|---|---|
| Fuel | 67% H2, 33% O2 | Orange | Autoignition at 573.15 K / 300 °C |
| HydroNox | 50% H2, 50% N2O | N/A | Autoignition at 323.15 K / 50 °C |
| Air | 75% N2, 25% O2 | White | 16 kPa Partial Pressure O2 minimum is required for human player breathing. Hyperoxia is not simulated.(NOTE: Suit air mixture should be 100% O2) |
Simulation Mechanics
- Ideal gas law (PV=nRT) is simulated.
- Thermal conductivity is not simulated. (f.e. heat is transferred at the same fixed rate for all substances; structures and devices are ignored)
- Thermal radiation is simulated. (caveat: radiated infrared is not absorbed by nearby objects)
- Phase change is simulated. (caveat: simplified and with fixed temperature for solid state)
- Fluid dynamics are not simulated. (caveat: thermal convection is partially simulated)
- Gravity is not simulated. Density is also not simulated. (gas pressure determines liquid pressure and liquid is present in all directions)
- Each environment grid cube acts as a single point.
- Connected pipes network act as a single point. (valves, pumps, mixers, etc act as pipe network splitter)
- All pumps/mixer also act as a check valve.
- Gas stoichiometry is not used. (H2O -> 2H2 + O2, 2H2 + O2 -> H2O, 4H2 + 2O2 + 300C -> 13CO2 + 5X)
- Pipes have arbitrary stress value determined by amount of non-correct phase of substance within them (liquid in a gas pipe).
- [bug?] Liquid temperature is controlled by gas temperature. (if no gas present, liquid heater will not function)
