    Numerical Simulation of Blood Flow with Sodium Alginate (SA) Nano Particles in Stenosed Human Arteries in the presence of Body Acceleration
    (2019-06) Fernandes, Ignatius
    Numerical simulation of blood flow with sodium alginate nano particles in stenosed human arteries in the presence of body acceleration is obtained. Effect of sodium alginate (SA) nano particles in the presence of body acceleration is observed on velocity, flow rate and resistive impedance to blood flow in stenosed human artery. The governing equations are discretized by explicit finite difference scheme. The discretized equations are the simulated using MATLAB. Velocity, flow rate and impedance to flow are observed to be influenced in the presence of both nano particles as well as body acceleration. The joint effect of nano particles and body acceleration is also observed. Resistance to flow is observed to be less in the presence of nano particles. This nano particle drug delivery may be useful for patients having cardiovascular diseases

    Simulation of Natural Convection in Blood Flow using Lattice Boltzmann Method
    (2019) Fernandes, Ignatius
    Lattice Boltzmann method is used to simulate natural convection in blood flow through stenotic artery. The problem of natural convection in stenotic artery is considered and the influence of elevated temperature and material properties is studied on the flow properties. A porous like square stenotic medium in a human artery with fluid (blood) at the left wall of the geometry and the north wall kept to a normalized temperature of 1.0 is considered. The flow properties like velocity profiles, streamlines, temperature profiles and the rate of heat transfer are then studied with respect to the material properties like porosity and permeability and flow parameters like Rayleigh number and power law index.
