 Following the type of simulation and the choice on the form of equations (dimensional, dimensionless, the scales used in order to define the non-dimensional form of equations, etc ...), the term $G_0$ can be written following different ways. For instance, the buoyancy force can be read as :  Following the type of simulation and the choice on the form of equations (dimensional, dimensionless, the scales used in order to define the non-dimensional form of equations, etc ...), the term $G_0$ can be written following different ways.
