Computational fluid dynamics (CFD) was for a longtime rigidly divided between simulating compressibleand incompressible flows, but a variety of importantflow phenomena like atmospheric flows arequasi-incompressible with significant densityvarations. Because of the good properties of schemesfor compressible flows, one asks the question: canthese methods cope with low Mach numbers? Fordecades the answer was somewhat fuzzy: Yes, inprinciple, but with deteriorating results fordecreasing Mach numbers.In this book we shed light on this phenomenon,showing that there are two sources of error: Theflux-...
