Validation Approach for CFD-Based Random Total-Pressure Data

摘要

Recent developments in eddy-resolving numerical methods have allowed time-accurate computational-fluid-dynamic models to compute turbulent flows w ithin aircraft inlet systems. Randomly fluctuating total pressure exiting a modeled inlet is available from these computations. This paper presents statistical-based approaches for validating random total-pressure data derived from time-accurate computational-fluid-dynamic models. The approaches include sample size selection, validation of steady-state total-pressure data, and validation of random total-pressure data.
