Engineers and physicists are always trying to describe their problems in the easiest form possible. Remember Sheldon Cooper’s joke about the hen and the egg? If not, don’t worry: The base assumption to make the solution of the problem work includes a spherical hen in a vacuum. Simplifying a problem for the vacuum case is usually the go-to starting point for any scientist challenged with a problem. Involving a fluid domain in your model increases the complexity drastically, adds a multitude of additional physical interaction processes to the system and made, just until a couple of decades ago, the process of solving the problem almost impossible. The field of Computational Fluid Dynamics is targeting exactly this problem of quantitatively describing all physical phenomena involved in a real fluid and determining a prediction model.
