... Of course, several DE’s which do not satisfy the hypotheses of this Theorem will also have integrating factors, but explicit formulas for them are difficult to obtain since they will generally depend on both x and y. However, the theorem does suggest a method for solving the DE M dx + N dy = 0 which ...

introduction to s-systems and the underlying power-law
... A general explicit solution for Ssystems appears to be impossible because they include as special cases well-known functions, such as the elliptical equations, which have no solution in terms of elementary mathematical functions (Courant, 1955). For these reasons we have focused attention on the dev ...

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.
