 November 26, 2005, 03:08 HOW to GET FLUCTUATING VELOCITY COMPONENT at FLUEN #1 Seyfettin Guest   Posts: n/a Hi everybody; I am currently using FLUENT and I am waiting an explanation on fluctuating velocity. I have been studying on a jet flow in crossflow. My turbulence model is Realizable k-epsilon. After the unsteady solution I want to get the fluctuating velocity components for having turbulence quantity. If anybody could gave me any info on the subject I would be very happy. Any answer will be appreciated. Thanks
