The velocity distribution inside and above the submerged vegetation can be divided into three zones from the bed surface to the water surface,The experiment results show that the mean velocity are increased humdrum,and then keep invariability,the velocity distribution reobey semi-logarithm distribution;The maximum of turbulent intensity in long.

Doppler ultrasound was used to measure SMA blood flow hemodynamic parameters including: PSFV (cms), TMFV (cms), EDFV (cms), RI .

The experimental results including the mean velocity field, fluctuating velocities and turbulent kinetic energy show that the structure of the velocity field varied with different immersing depths of the impeller in the stirred tank.

The f-Re relationship and formula for mean velocity in smooth region of turbulent open channel flow with hyperconcentrated sediment;

The influence of aeration on average velocity of self-aerated chute flow;

Research on application of fuzzy optimization neural network model to debris flow average velocity forecasting;

Based on the Nikurades velocity distribution formula in the round pipe fluid flow,combining with the experiment results of fluid mechanics,the relationships between the average velocity and radius of round pipe are given,which offers the basis for the design of the flow meter applying Pitot pipe theory.
