“…The quantitative results of the α, β, n, δ, N t , andN b for diverging tapering, converging tapering, and non-tapered arteries are observed physically in Figures 2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22 that with an increase in the thermophoresis parameter N t and stenosis shape n, the velocity profile decreases, while velocity profile increases with an increase in the maximum height of the stenosis δ, Brownian motion parameter N b , and Prandtl parameters α and β. It is also seen that for the case of converging tapering, it has a larger value as compared with the case of diverging tapering and non-tapered arteries.…”

Nanoparticle analysis for blood flow of Prandtl fluid model with stenosis

2013

In this article, we have discussed blood flow in the nano-Prandtl fluid flow analysis in tapered stenosed arteries. The occurrence of nanoparticle fraction and heat transfer was found. Gravitational effects were also considered because the tube was taken vertically upward. Homotopy perturbation method was used to find the analytical solution of coupled nonlinear differential equations. Physical features have been discussed through graphs of concentration profile σ , velocity profile w, resistance impedance λ, temperature profile θ , wall shear stress S rz , wall shear stress at the stenosis throat τ s , and the stream lines.

Effect of heat and mass transfer on the blood flow through a tapered artery with stenosis is examined assuming blood as Jeffrey fluid. The governing equations have been modelled in cylindrical coordinates. Series solutions are constructed for the velocity, temperature, concentration, resistance impedance, wall shear stress and shearing stress at the stenosis throat. Attention has been mainly focused to the analysis of embedded parameters in converging, diverging and non-tapered situations

“…They visualized that the shape of the stenosis in the arterial lumen is chosen to be irregular in order to improve resemblance to the in-vivo situation. Rheological properties of blood have been taken into account through the constitutive equations of a micropolar fluid by Abdullah et al [3], according to their analysis blood exhibits non-Newtonian characteristics at low shear rates. Mekheimer and El Kot [4] also discussed the blood flow analysis for micropolar fluid model for axisymmetric but radially symmetric mild stenosis tapered artery.…”

In this article, we have examined biomechanical analysis of Eyring Prandtl fluid model for blood flow in stenosed arteries. Blood flow in arteries is an important phenomenon from biological and medical point of view. No one can survive without blood flow in tapered arteries. Blood flow is the continuous running of blood in the cardiovascular system. The human body is made up of several processes all carrying out various functions. We have the gastrointestinal system which aids the digestion and the absorption of food. We also have the respiratory system which is responsible for the absorption of O 2 and elimination of CO 2 . The urinary system removes waste from the body. The cardiovascular system helps to distribute food, O 2 and other products of metabolism. The reproductive system is responsible for perpetuating the species. The nervous and endocrine system is responsible for coordinating the integration and functions of other system. The equations govern the flow for considered model are presented in cylindrical coordinates. Perturbation solutions are developed in terms of small Eyring Prandtl fluid parameter β for the velocity, impedance resistance, wall shear stress and shearing stress at the stenosis throat. Three types of arteries i.e converging, diverging and non-tapered arteries have been considered for the analysis and discussion. Graphical results have been presented for different physical parameters of the flow problem. Streamlines have been plotted at the end of the article. We observed that due to increase in Eyring Prandtl fluid parameter α, β the stenosis shape n and maximum height of the stenosis δ the velocity profile increases.
