Many of the flows occurring around us can be classified into turbulent flows. For laminar flows, the flow spatial structures are relatively simple and their calculations tend to be easier than for the turbulent flows. It is rather difficult to calculate the turbulent flows. Moreover understanding the movement mechanisms for each spatial structure of turbulent flows is not a simple matter. In this work, by using a Reynolds number experimental apparatus, we observed the stream lines formed inside the experimental pipe during quantitatively studying the relation between the Reynolds numbers and the flow regimes of laminar and turbulent. In addition, the fluid velocity distributions have been analyzed by our carrying out simulations of the flows established during the experimental studies with CFD Phoenics, the heat fluid analysis software.
