Detailed Description

A model for nucleation site density based on Lemmert-Chawla (1977) function and Egorov-Menter (2004) correlation for boiling flows.

Usage

Example of the model specification:

nucleationSiteModel
{
    // Mandatory entries
    type            LemmertChawla;

    // Optional entries
    Cn              <scalar>;
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`type`	Type name: LemmertChawla	word	yes	-
`Cn`	Coefficient for nucleation site density	scalar	no	1.0
