Methods

GetGas

Use: GetGas(User input)

Returns a read-only Gas object containing information for a given gas.

If no gas is found that can match the input, throws an error.

Phase change methods

Evaporation Pressure

EvaporationPressureUnclamped

Use: EvaporationPressureClamped(gasTable, Temperature)
gasTable: a table containing information for a given gas (obtainable through GetGas)
Temperature: The current gas gemperature in kelvin

Evaluates the gas's evaporation pressure curve for a given Temperature, returning its corresponding evaporation pressure in kPa. This is just the curve function without any compensation for phase change characteristics.

EvaporationPressureClamped

Use: EvaporationPressureUnclamped(gasTable, Temperature)
gasTable: a table containing information for a given gas (obtainable through GetGas)
Temperature: The current gas gemperature in kelvin

Evaluates the gas's evaporation pressure curve for a given Temperature, returning its corresponding evaporation pressure in kPa. Unlike EvaporationPressureClamped, this first clamps the input temperature to values within the range where the gas can exist as a non-frozen liquid.

EvaporationPressure

Use: EvaporationPressure(gasTable, Temperature)
gasTable: a table containing information for a given gas (obtainable through GetGas)
Temperature: The current gas gemperature in kelvin

Evaluates the gas's evaporation pressure curve for a given Temperature, returning its corresponding evaporation pressure in kPa. Unlike the other methods, this provides additional handling to return the evaporation pressure for supercooled liquids when given a liquid as input.

Evaporation Temperature

EvaporationTemperatureUnclamped

Use: EvaporationPressureUnclamped(gasTable, Pressure)
gasTable: a table containing information for a given gas (obtainable through GetGas)
Pressure: The current gas pressure in kPa

Evaluates the gas's evaporation pressure curve for a given Pressure, returning its corresponding evaporation temperature in kelvin. This is just the curve function without any compensation for phase change characteristics.

EvaporationTemperatureClamped

Use: EvaporationTemperatureClamped(gasTable, Pressure)
gasTable: a table containing information for a given gas (obtainable through GetGas)
Pressure: The current gas pressure in kPa

Evaluates the gas's evaporation pressure curve for a given Pressure, returning its corresponding evaporation temperature in kelvin. Pressure values are clamped to the range of values the gas can exist as a non-frozen, non-supercritical liquid.

EvaporationTemperature

Use: EvaporationTemperatureClamped(gasTable, Temperature)
gasTable: a table containing information for a given gas (obtainable through GetGas)
Pressure: The current gas pressure in kPa

Evaluates the gas's evaporation pressure curve for a given Pressure, returning its corresponding evaporation temperature in kelvin. This is currently the same as EvaporationTemperatureUnclamped(gasTable, Pressure).

Objects

Gas

A table containing data for a gas. Editing these should be done through Module:Gas/data.

Fields

See Module:Gas/data/doc.

 =====Fields=====
-======Name======
+See [[Module:Gas/data/doc]].
-An internal name for a given gas, PascalCased. For spaces, use '''HumanReadableName''' instead.
-======ID======
-The internal mask for a given gas, as an integer value.
-======HumanReadableName======
-A human-readable name for a given gas.
-======HumanReadableSymbol======
-A community-defined symbol for a given gas. This does not necessarily match the symbol used ingame. Liquids have the same symbol as their matching gas.
-======MolarMass======
-The molar mass for a given gas in g/mol.
-======HeatCapacityRatio======
-The heat capacity ratio fot a given gas. Adiabatics is only currently used in rocket exhaust velocity calculations.
-======Image======
-An URI to an image of the gas on this wiki.
-======State======
-The gas's state. Can be either '''Gas''' or '''Liquid'''.
-======MolarVolume======
-Volume taken by 1 mol of gas in liters. Only present in ''Liquid''s.
-======SpecificHeat======
-The gas's specific heat in J/mol*K.
-======LatentHeat======
-The gas's phase change latent heat in J/mol.
-======CondensesInto======
-The [[Gas/doc#Name|Name]] of the liquid the gas condenses into during phase change. Only present on Gases capable of condensing into liquids.
-======EvaporatesInto======
-The [[Gas/doc#Name|Name]] of the gas the liquid condenses into during phase change. Only present on Liquids capable of evaporating into gases.
-======EvaporationRatio======
-Multiplier for the energy of the gas the liquid evaporates into. Used for liquids that phase change into gases with different heat capacities (Alcohol / Liquid Sodium Chloride).
-======TriplePressure======
-The gas's evaporation pressure at its triple point in kPa.
-======CriticalPressure======
-The gas's evaporation pressure at its maximum liquid temperature in kPa.
-======A======
-Evaporation Coefficient A for the gas.
-======B======
-Evaporation Coefficient B for the gas.
-======FreezingTemperature======
-Temperature in kelvin at which the gas freezes.
-======CriticalTemperature======
-Temperature in kelvin at which the gas can no longer condense regardless of pressure.
-======Enthalpy======
-Enthalpy of combustion for the gas in J/mol. 0 for non-[[fuel]]s.
-======AutoignitionTemperature======
-Temperature at which autoignition occurs in Oxygen for fuels(or spontaneously for [[Hypergol]]s).
-======IsHypergol======
-Boolean on whether autoignition can occur without an oxidizer. Only true in the case of [[Hydrazine]] and its liquid counterpart.
-======AutoignitionOffset======
-How far the oxidizer reduces autoignition temperatures for fuels that combust with it.
-======EnthalpyMultiplier======
-Multiplying factor for the fuel's combustion enthalpy when combusting with a fuel. 2 for [[Nitrous Oxide]] and [[Ozone]], 1 for everything else.
-======ThermalEfficiency======
-The heat-to-energy conversion efficiency for the gas when it's used in a [[Stirling Engine]].
