Experimental data needs for computational fluid dynamics - A position paper
Abstract
The interaction between experimental data and computational fluid dynamics is discussed. Since a need for approximate methods of computation of turbulent flows at high Reynolds numbers will continue to exist, a data base will continue to be needed to build simulation models and to substantiate approximations. The requirements for this data base are discussed. Specific needs in experimentation are addressed, including the need for initial and/or boundary data complete enough to specify a test case, and for profile measurements of the mean flow and turbulence quantities. The importance of measuring the flow field to obtain a complete picture of the real physics of flow and of reporting sufficient information is stressed. Boundary conditions are considered, and those results necessary to check the computational output are distinguished. The data needs for large-eddy simulation models are assessed.
