Verification and validation (V&V) serve critical roles in ensuring that numerical predictions are relevant for engineering analysis. Traditionally, CFD results have been used for guidance but are heavily dependent upon being anchored by test data. As CFD capabilities are being increasingly used to perform more varied analyses, more rigorous applications of V&V are critical. Careful and relevant validation provides the confidence in CFD results that decision makers require, but most present methods do not include consideration of uncertainty to provide an indication of sensitivities in CFD solutions. Between advancements in computing power and additional numerical techniques, this type of analysis is now possible and can be used to provide rigorous validation.
