This field, which includes traditional computational fluid dynamics, combustion, hypersonics, chemically reacting flows, environmental pollution and contamination modeling, weather prediction, direct numerical simulation of turbulence, and turbulence modeling, has suffered from a flawed philosophy advocated in the past by some agencies that the size and speed of available ~ e ~ ~ ~ ~ , ~ me, e ~ computers will drive the advances in CFD, making research on methodology of secondary importance. Recent developments prove that a contrary philosophy is needed for the healthy growth of CFD over the next decade.
