Abstract: The present work compares the results from a Large Eddy Simul ation (LES) and the result of two Laser Doppler Velocimetry (LDV) measurements. The work focuses on a model of a vor- tex flow meter, a common flow meter type in process industry. It s measuring principle is that the frequency of a vortex street, generated by a shedder bar, is acquired by pressure or velocity sensors. The shedding frequency is proportional to the bulk flow rate. Tests are performed at a Reynolds number of 61400, based on the pipe diameter. A compl ementary LDV measurement is also performed at a Reynolds number of 62800. All results are normalized with the bulk velocity to be comparable to each other. A comparison of the mean strea mwise velocity profiles shows excellent agreement between the numerical and experimenta l methods. The variance of the two velocity components is also in good agreement between the in vestigated results.
