N2 - As part of an analysis of Ultrasonic Flow Meters (UFMs), The Ohio State University has utilized the FLUENT 6.1 and Virtual UFM (VFUM) computer codes to model the feedwater velocity profiles and compute the Profile Factor (PF) that would be obtained by a 4-chord time of flight ultrasonic flow meter. The geometry used in the simulation was designed to be similar to that found in the Watts Bar Nuclear Power Plant. The effect of variation in the length between two out of plane 90 degree bends was investigated. Swirl was detected in all cases reviewed. The profile factors are greater than 1.0 in all cases. In most cases, the profile factor does not decrease monotonically as the distance downstream from the second bend increases. It appears that the numerical techniques used here give added insight to where a UFM ought to be placed in a plant.
