MolViscPerturbModel (Case)#

Defines the model used for fluctuating molecular viscosity in FELiCS.

Type
dictionary
Default
{"type":"Constant","Constants":{"Viscosity":1.0}}

Accepted values

Description

"Constant"

Assume a frozen molecular viscosity

"Sutherland mean"

Computes fluctuating molecular viscosity using a linearized Sutherland-law model around the mean temperature

Example#

The parameter should be provided as a dictionary containing:

  • "type": perturbation model name,

  • "Constants": dictionary containing model-specific constants.

"Case": {
    "MolViscPerturbModel": {
        "type": "Sutherland mean",
        "Constants": {
            "Ts": 170.672
        }
    }
}

For "Constant", the following constant is currently required:

  • "Viscosity": constant fluctuating viscosity value.

For "Sutherland mean", the following constant is currently required:

  • "Ts": Sutherland temperature constant.
