Verification and Validation in Computational Fluid Dynamics and Heat Transfer: PTC 61

ASME Codes and Standards created a new Performance Test Code Committee in May of 2004, whose primary focus is on the formalization of an approach to the process for verification and validation in computational fluid dynamics and heat transfer. PTC-61 has as its charter to provide “procedures for quantifying the accuracy of modeling and simulation in computational fluid dynamics and heat transfer.” The committee is initially focusing on an approach based on the concepts and methods of experimental uncertainty analysis. This will leverage the decades of development 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.” This paper provides a brief summary of the status of the PTC-61 effort to develop a standard for V&V.
