Detailed Description

Linear concentration dependent density model.

$\varrho = \varrho_{\text{ref}} (1 + \bar \alpha (C - C_{\text{ref}}) + \bar \beta (p - p_{\text{ref}}) )$

where

$\varrho_{\text{ref}}$ is the reference density
$\bar \alpha$ is the fluid density concentration difference ratio
$C_{\text{ref}}$ is the reference concentration
$\bar \beta$ is the fluid density pressure difference ratio
$p_{\text{ref}}$ is the reference pressure
