Two and Three Dimensional Blood Flow Simulations in Different Types of Blood Vessels
Journal Title: INCAS BULLETIN - Year 2015, Vol 7, Issue 4
Abstract
In this paper we present a synthesis of our results obtained on blood flow simulation in different types of blood vessels. We present first some remarks on the wall shear stress (WSS) in the case of a human abdominal aortic aneurysm (AAA), and then we concentrate on the mechanical conditions which would lead to the “rupture” of the vascular vessel with aneurysm and implicitly to a possible stroke. We also make some investigations on the Fahraeus-Lindqvist effect in arterioles. Considering an axial-symmetric reservoir full of blood and which is linked to an arteriole (with the same particular geometry), we have pointed out the concentration of the red blood cells in this arteriole towards the core of the vessel. To improve our work we have considered a real three-dimensional geometry, which is a serious jump versus our previous results, where only the axial-symmetric geometries were considered. In this respect we have reconsidered the case of a carotid artery stenosis with and without a stent.

Comparative study between random vibration and linear static analysis using Miles method for thruster brackets in space structures
Random vibrations occur during the launch at the fastening interface between thruster brackets and basic support of satellite. These are generated in the launcher by the motion of some mechanical parts, combustion phenom...
Aerodynamic Interference between Oscillating Lifting Surfaces and Fuselage. Part 4: Flapping and Pitching WingsLaws for Micro-Air Vehicles (MAV) in Straight Flight
In the fourth article of our series we continue to deal with the calculation of the aerodynamic unsteady forces on lifting surfaces. Now we present some applications of the theory discussed in the previous papers to the...

An Interpretation of the “Black Energy” in Universe by Using a Hydro-Dynamical Analogy with Newton Gravity
There are arguments proving that what we see now as “normal energy” (including the equivalent mass-energy) represents only 5% of the total energy of the Universe [1]. The rest is invisible meaning that no widely accepted...
