Verification and validation in computational fluid dynamics and heat transfer using experimental uncertainty analysis concepts

An approach to verification and validation (V&V) using experimental uncertainty analysis concepts to quantify the result of a validation effort is discussed. This is the approach to V&V being drafted by the American Society of Mechanical Engineers (ASME) Performance Test Code Committee, PTC 61: Verification and Validation in Computational Fluid Dynamics and Heat Transfer. The charter of the committee is "Provides procedures for quantifying the accuracy of modeling and simulation in computational fluid dynamics and heat transfer." The committee is initially focusing its efforts on drafting a standard for V&V in computational fluid dynamics and heat transfer based on the concepts and methods of experimental uncertainty analysis. This will leverage the decades of effort in the community of experimentalists that resulted in the ASME Standard PTC 19.1 "Test Uncertainty" and the ISO international standard "Guide to the Expression of Uncertainty in Measurement."
