The first equation is called the Continuity equation. This balance equation states the principle of conservation of mass, i.e. mass can neither be created nor destroyed [1]; Thus the right-hand side of the equation is equal to zero. | The first equation is called the Continuity equation.

For the augmented reality a reference object and the CFD sequence are needed. The reference object was created with the help of Fusion360, the idea was to create a sphere illustrating the mesh used in the CFD process. After that, the model was 3D printed and mounted in a base. | For the augmented reality a reference object and the CFD sequence are needed.
