THE INVESTIGATION OF UNCERTAINTY FOR THE CFD RESULT VALIDATION

CFD 해석결과 검증을 위한 불확실도 연구

An approach to CFD code validation is developed that gives proper consideration to experimental and simulation uncertainties. The comparison errors include the difference between the data, simulation values and represents the combination of all errors. The uncertainties of modeling and numerical analysis in the CFD prediction were estimated by a Coleman's theory. In this paper, the numerical solutions are calculated by A-type standard uncertainty and Richardson extrapolation Method.
