The displacements of the fan surface were captured by two - cameras high-speed correlation system. The obtained data exported from some chosen points were for the purposes of post-processing imported into Matlab. For a verification of the reached results the second independent experimental method was used - the determination of the cooling fan rotational frequency was performed by a digital-optic tachometer. http://pubs.sciepub.com/ajme/1/7/27/ajme-1-7-27.pdf high-speed digital image correlationmotion analysiskinematic quantities
