Detailed Description

Linear concentration dependent density model.

\[ \varrho = \varrho_{\text{ref}} (1 + \bar \alpha (C - C_{\text{ref}})) \]

where

\( \varrho_{\text{ref}}\) is the reference density
\( \bar \alpha\) is the fluid density difference ratio
\( C_{\text{ref}}\) is the reference concentration
