10. , fire) where there is a strong density variation with temperature, density emerges as part of the solution everywhere within the flow domains. The density of the particular fluid flowing into these domains at the inflow boundaries needs to be specified and is usually determined directly from the imposed temperature and pressure. However, no boundary conditions are required for the density at the outflow boundaries, since the fluid density replicates the outgoing fluid characteristics through these boundaries.

More often than not, in-depth experience with the selection of appropriate values of these factors can only be gained by extensive investigation of a variety of flow problems. Estimating the errors (Chapter 5) introduced by an inadequate mesh design for a general flow can be rather arduous. Preparing a good initial mesh design usually requires foreknowledge of, or insight into, the expected properties of the flow. In dealing with the coarseness of a mesh, the only way to eliminate the errors is to embrace the procedure of successive refinement of an initially coarse mesh until certain key results exhibit no appreciable changes.

With the surging demand for CFD to solve a spectrum of fluid-related problems, the ability to properly employ this methodology has never been as important as it is in the current climate. 13 Which industry has CFD emerged from? Which three disciplines is CFD derived from? Traditionally, CFD has been used to solve aerospace and automotive engineering applications, such as drag and lift for airplanes and cars. What examples can you think of where CFD is being used within non-traditional fluid-engineering applications?
