RISComparison of the V&V10.1 and V&V20 Modeling Error Quantification Procedures for the V&V10.1 Example
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The determination of the transverse tip deflection of an elastic, hollow, tapered, cantilever, box beam under a uniform loading applied over half the length of the beam presented in the V&
Estimation of Discretization Errors in Viscous Flow Simulations Based on the RANS Equations: Wall-Resolved Versus Wall-Functions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present paper, we focus on the simulation of viscous flows at high Reynolds numbers using the Reynolds-averaged Navier–Stokes (RANS) equations. Time-averaging is used to define the mean flow properties and only ...
On the Failure of the Area Metric for Validation Exercises of Stochastic Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses the application of the area metric to the quantification of modeling errors. The focus of the discussion is the effect of the shape of the two distributions on the result produced by the Area Metric. ...
On the Interpretation and Scope of the V&V 20 Standard for Verification and Validation in Computational Fluid Dynamics and Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The goal of this paper is to summarize and clarify the scope and interpretation of the validation procedure presented in the V&
Assessment of Discretization Uncertainty Estimators Based on Grid Refinement Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the assessment of the performance of nine discretization uncertainty estimates based on grid refinement studies including methods that use grid triplets and others that use a largest number of data ...
Overview of the 2018 Workshop on Iterative Errors in Unsteady Flow Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two workshops were held at the ASME V&V Symposiums of 2017 and 2018 dedicated to Iterative Errors in Unsteady Flow Simulations. The focus was on the effect of iterative errors on numerical simulations performed with ...
