Approach to some Properties near the Wall of Parallel to Wall Shear Flow

From the viewpoint of vortex dynamics, the flowing properties and the characters of transition from laminar flow to turbulent flow were analyzed, the concept of the Reynolds number was reviewed and studied. The different form of the Reynolds number was presented to relate it with fluctuating and breaking down processes to show its dynamical mechanism. On the basis of phenomenological properties, the velocity distribution near the wall was studied to show that the profile connects with the flowing structure which is different from the linear form what usually considered to be, thus the velocity distribution near the wall remains open. Finally, the form of the velocity distribution should follow was probed.
