Blood pulse is an important human physiological signal commonly used for the understanding of the individual physical health. Current methods of non-invasive blood pulse sensing require direct contact or access to the human skin. As such, the performances of these devices tend to vary with time and are subjective to human body fluids (e.g. blood, perspiration and skin-oil) and environmental con...

INTAGLIETTA, M., D. R. RICHARDSON, AND W. R. TOMPKINS, Blood pressure, flow, and ehtic properties in microvessels of cut omentum. Am. J. Physiol. 221(3): 922-928. 1971.-Pressure was measured in vivo in the microvessels of the cat omentum with a servonulling instrument. Velocity of red blood cells was determined simultaneously by an online dual-slit photometric technique. Cross correlation with ...

A novel Particle Tracking Velocimetry (PTV) algorithm based on Voronoi Diagram (VD) is proposed and briefed as VD-PTV. The robustness of VD-PTV for pulsatile flow is verified through a test that includes a widely used artificial flow and a classic reference algorithm. The proposed algorithm is then applied to visualize the flow in an artificial abdominal aortic aneurysm included in a pulsatile ...

In this paper, we study the pulsatile flow of blood through stenotic arteries. The inner layer of arterial walls is modeled as a porous medium and human blood is assumed as an incompressible fluid. A numerical algorithm based on the finite element method is developed to simulate the blood flow through both the lumen region and the porous wall. The algorithm is then applied to study the flow beh...

The aorta is the largest artery that delivers blood from the heart to the rest of the body, and many cardiovascular diseases often occur on the aortic arch. The complex mechanical interaction between pulsatile blood flow and wall dynamics in the aortic arch model was simulated by means of computational loose coupling fluid-structure interaction analyses. This study investigates the pulsatile fl...

Atherosclerotic plaque can cause severe stenosis in the artery lumen. Blood flow through a substantially narrowed artery may have different flow characteristics and produce different forces acting on the plaque surface and artery wall. The disturbed flow and force fields in the lumen may have serious implications on vascular endothelial cells, smooth muscle cells, and circulating blood cells. I...

Physiol. 226(l) : 90-95. 1974.Dorsal and ventral aortic blood flows have been recorded in cod and the flows compared with results from hydraulic and electrical models of the fish circulatory system. In the hydraulic model increase in “dorsal aort...
