... A system [also called a closed system] is a quantity of matter of fixed identity. No mass can cross a system boundary. A control volume [also called an open system] is a region in space chosen for study. Mass can cross a control surface (the surface of the control volume). The fundamental cons ...

... (c) For each y in 0 < y ≤ K, show that dy/dt as given by the Gompertz equation is never less than dy/dt as given by the logistic equation. 17. (a) Solve the Gompertz equation dy/dt = ry ln(K/y), subject to the initial condition y(0) = y0 . Hint: You may wish to let u = ln(y/K). (b) For the data give ...

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.
