Validace CFD výpočtů s experimentálními daty, metody a jejich přesnost

Validation and verification are the processes which could the virtual reality of CFD simulations bring closer to physical reality. The key role in those processes play the method of quantification of similitude of the different situations in the flow-field, thus the metric, which should be properly chosen. In the verification process the proper strategy of the mathematical model modification should be adopted, while in the validation process the proper experimental data should be utilized. The experimental data is used also for the boundary condition definition. The present paper deals with those aspects
