Comparison between PIV measurement (left) and the result of CFD numerical simulation (right).
Non-contact measurement techniques conventionally used in other measurement fields have been exploited also in fluid dynamics. For example laser Doppler interferometry applied for solid vibration measurements has been used for the acoustic characterization of fluid flows giving rise to a new technology called tomographic Doppler laser interferometry.
