Computational Fluid Dynamics Analysis

**Backgound **
Computational Fluid Dynamics (CFD) is a method of calculating the velocity, pressure and
temperature fields in a region of space occupied by a fluid. Essentially the space is divided up
into a large number of small volumes (cells) defined by a 3 dimensional grid. The non linear
partial differential equations governing the conservation of mass, momentum and energy in the
fluid are then solved by a numerical method on a computer. Because the region of space is
being artificially separated from its surroundings it is necessary to define the conditions the
fluid experiences on the boundaries of the region (the boundary conditions) since this will
influence the flow of fluid inside. The more accurately the boundary conditions and surrounding
geometry can be specified the more accurate will be the calculation inside the region.
