Turbulent velocity profile measurement in circular pipe flow using particle image velocimetry technique

Experimental study of turbulent flow in circular pipe is carried out by using PIV technique as a preliminary experiment for studying thermo fluid properties of molten salt, Flibe in particular, which is a high Prandtl number fluid. At this first stage, water is used as working fluid to obtain reference data. Measurements of the fully developed turbulent flow in a circular pipe at Re = 5286 are carried out using PIV system and near wall flow structure and turbulent statistics as well as averaged flow field are obtained. Average velocity profile has good agreement with the DNS data.
