Although Ref. 5 cited the 2003 version of Ref. 1, it did not include the bracketed term added to the original 1996 issue of Ref. 1.

J. Fluids Eng 131(3), 034503 (Feb 04, 2009) (4 pages) doi:10.1115/1.3077134 History: Received June 19, 2008; Revised December 22, 2008; Published February 04, 2009

Ambiguities, inconsistencies, and recommended interpretations of the commonly cited definition of validation for computational fluid dynamics codes/models are examined. It is shown that the definition-deduction approach is prone to misinterpretation, and that bottom-up descriptions rather than top-down legalistic definitions are to be preferred for science-based engineering and journal policies, though legalistic definitions are necessary for contracts.
