... The Froude number is a ratio of inertial to gravitational forces for a fluid. It compares the tendency of a moving fluid to continue moving with the gravitational forces that act to stop its motion. Froude number = Fr = flow velocity/(acceleration of gravity)(force of inertia) = V/√gD Where D = dept ...

Computational fluid dynamics
Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial experimental validation of such software is performed using a wind tunnel with the final validation coming in full-scale testing, e.g. flight tests.
