Permeability changes in vessels following blood loss
A study was made of the effect of various amounts of blood loss on general blood vessel permeability to substances of low molecular weight.
In this paper it is the objectives to investigate the effect of the channel boundary on the mean and turbulence structure in a trapezoidal open channel. Precise velocity measurements were carried out by using a Laser Doppler Anemometer, and two kinds of flow visualization techniques were used to investigate the three-dimensional structure of turbulent flow in several trapezoidal open channels.Secondary flow and its induced secondary fl ow cells were directly visualized by the refined tracer method. Some attractive photographs are shown in this paper. The results show that secondary flow cells affect on the distribution of the boundary shear stress.
