Abstract: The results of numerical simulations can be validated experimentally, but usually only the aggregate characteristics are compared. If the aggregate and partial characteristics can be compared at the same time, the level of trust is increased and the physics can be studied in detail. This paper presents a modular measurement system incorporating several devices, including a PIV, traverse system, NI CompactRIO and/or a DAQ, which are synchronized and enable the simultaneous acquisition of aggregate and partial parameters at various sampling frequencies. The modular concept allows for easy configuration and adjustments as needed. The high DI sampling frequency achieved by the CompactRIO system enabled the analysis of trigger delay and significantly increased the AI capability of the PIV system.
