OBJECTIVE AND SCOPE

The objective of this Standard is the specification of a verification and validation approach that quantifies the degree of accuracy inferred from the comparison of solution and data for a specified variable at a specified validation point. The approach, proposed by Coleman and Stern [1], uses the concepts from experimental uncertainty analysis [2-4] to consider the errors and uncertainties in both the solution and the data.

The scope of this Standard is the quantifi cation of the degree of accuracy of simulation of specifi ed validation variables at a specifi ed validation point for cases in which the conditions of the actual experiment are simulated. Consideration of solution accuracy at points within a domain other than the validation points (e.g., interpolation/ extrapolation in a domain of validation) is a matter of engineering judgment specifi c to each family of problems and is beyond the scope of this Standard.

Fluid dynamics and heat transfer are the areas of engineering and science that are specifi cally addressed, but the validation approach discussed is applicable in other areas as well. Discussion and examples are centered on models using partial differential equations, but simpler models also fall within the purview of the validation approach.
