Specification of density and vapor fraction (RhoX flash)

Compute the properties of a given fluid, at a fixed density and vapor fraction.

Function signature

XLT.REF.FLASH.RHOX(Fluid, Rho, X, Properties, [in-units], [out-units])

Function parameters

The function takes the following arguments:

Fluid: TEXT

The name of the fluid. The list of available fluids can be found here.

Rho: NUMBER

The density at which the properties are to be computed. The density unit depends on the units specified in the in-units parameter. The default unit is kg/㎥.

X: NUMBER

The vapor fraction at which the properties are to be computed. The value must be between 0 and 1.

Properties: TEXT or TEXT array

The list of properties to be computed. The list of available properties can be found here.

in-units: TEXT [optional]

A string specifying the units of the temperature and pressure. The default unit is SI. The list of available units can be found here.

out-units: TEXT [optional]

A string specifying the units of the properties. The default unit is SI. The list of available units can be found here.

Function results

Returns a value, or an array of values, corresponding to the list of properties of the fluid at the given density and vapor fraction.
