... 4. Non-uniform body forces (example, forces exerted by a spinning propeller on air particles) can cause different fluid particles to be accelerated differently, causing a non-uniform velocity field. Result: Rotation. Although most flows encountered in nature are rotational, if we stay away from visc ...

An alternative quadratic formula
... The correctness of the formula is readily checked by expanding the square and comparing to (4). By looking at (9), we read off that, for real coefficients u, v 2 ∈ R, (8) has • a double root (namely 2u) iff u = ±v, • two distinct real roots iff u2 > v 2 , • two real roots of opposite sign iff v 2 < ...

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.
