CFD analysis of pulsatile blood flow in an atherosclerotic human artery with eccentric plaques

Haemodynamic study of Flow in concentric and eccentric stenosed carotid Artery

“…The velocity contours, WSS and pressure have been considered in the present study for comparing the deviation in the flow. In the high grade stenosis, the flow resistance in arteries increases, which forces the body to raise the blood pressure to maintain the necessary blood supply [4]. Both the high pressure and the narrowing of blood vessel cause high flow velocity, high shear stress and low or negative pressure at the throat of the stenosis, low shear stress and flow separation at the distal side of the stenosis [5].…”

“…The flow behavior in case of ECN at the downstream of stenosis is characterized by flow separation leading to formation of eddies and in the case of CCN, the flow jet extends to larger length causing vortices. This behavior gets complex as the severity of stenosis increases [4,5]. Further, the hypothetical cases of increased severity were used in prediction of changes in flow behavior as the percentage of stenosis increases.…”

“…The study of stenosis, which is a constriction in the blood vessels, can be helpful in understanding the biomechanics of vascular diseases. The flow behavior in the stenosed artery is quite different than one in the normal arteries [4,5].…”

Effect of blade installation angle on power efficiency of resistance type VAWT by CFD study

“…In accordance with the simulation of Savonius wind turbine [13][14][15][16][17][18][19][20][21][22], it could draw lessons from the effective digging to the ''external potentiality'' for improving the power efficiency. In fact, the ''inner potential'' for improving power efficiency is still need to dig.…”

Haemodynamic study of Flow in concentric and eccentric stenosed carotid Artery

“…This type of study will be useful to predict the outcome of severity of stenosis, and aids the physicians with better insight into flow dynamics. Moreover it is also observed that severity less than 75% is considered as mild and anything greater than this is termed as critical [4,10]. This type of study will be useful to predict the outcome of severity of stenosis, and aids the physicians with better insight into flow dynamics.…”
