... (c) (1 point) If f has a saddle point at (a, b) then f cannot have a local minimum at (a, b). Solution: T (The definition of “saddle point” precludes it from being a local maximum or minimum) (d) (1 point) If f is differentiable at (a, b, c) then magnitude of the gradient vector ∇f (a, b, c) is the ...

SECTION 4.6 4.6 Logarithmic and Exponential Equations
... In Section 4.4 we solved logarithmic equations by changing a logarithm to exponential form. Often, however, some manipulation of the equation (usually using the properties of logarithms) is required before we can change to exponential form. Our practice will be to solve equations, whenever possible, ...

... Experimental data are needed to enable quick and accurate vortex modelling. These data are coming up to now mostly from wind tunnels which can not simulate the ‘real’ Reynolds and Mach number. Thereby it is usually assumed that this mismatch does not affect the results. Klinge et al [1] showed that ...

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.
