Methods

GetGas

Use: GetGas(User input)

Returns a lua table 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).
