HeliumFluidProperties
Fluid properties for helium
Description
The HeliumFluidProperties
class provides fluid properties for helium Petersen (1970).
The standard deviation for density is approximately 0.03% at a pressure of 0.1 MPa and 0.3% at 10 MPa, or
where is in MPa. The isobaric and isochoric specific heats are constant, with an uncertainty at 273 K of 0.05% at 0.1 MPa and 0.5% at 10 MPa. At higher temperature, the standard deviation is lower, and approximately
where K, is in MPa, and is in K. The standard deviation of the dynamic viscosity is approximately 0.4% at 273 K and 2.7% at 1800 K, or approximately
where is in K. The standard deviation of the thermal conductivity is approximately 1% at 273 K and 6% at 1800K, or
where is in K. The speed of sound is calculated as Harlow and Amsden (1971)
Range of Validity
The HeliumFluidProperties UserObject is valid for:
273.15 K 1800 K and
0.1 MPa 10 MPa.
