... Solve the difference equation by Galerkin’s method. Solution. Define the basic function for i =0 through 4 as follows: u0 = 2, u1 = sin x, u2 = cos x = 1, u3 = sin 2x, u4 = cos 2x - 1 Function u0 satisfies the boundary condition (5.11), and the rest satisfies zero boundary conditions.

Motion with Air Resistance
... The dissipative force in air or other fluids can generally be expressed in the form: fdiss = α v + β v 2 . Either term on the right-hand side of this equation may be important, depending on circumstances. The first term is most likely to be important in low-speed, streamline flows—typically where a ...

A classic new method to solve quartic equations
... Polynomials of high degrees often appear in problems involving optimization, and sometimes these polynomials happen to be quartics, but this is a coincidence. It is shown that any degree-n polynomial with rational (or real, or complex) coefficients has n complex roots. (This fact is called the funda ...

... In some sense measures fluidity of a fluid. Actually it is the resistance offered by a layer of fluid to the motion of an adjacent one. Consider the two-plate experiment. In case of a fluid in between them, we know that the upper plate moves with a speed U whereas the lower plate does not move. This ...

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.
