AbstractIn this thesis implementation of Lattice Boltzmann method for simulation of non Newtonian blood fluid flows is considered Several non Newtonian models are introducedand analytic solutions where possible are derived Among these non Newtonian models those which have been used for blood flow are considered in particular Furthermore someabnormal characteristics of blood flow and effects of blood cells on blood flow propertiesare explained In the present work numerical results of lattice Boltzmann simulation ofNewtonian fluid flow between two parallel plates are presented Several boundaryconditions namely periodic entrance velocity and constant pressure are used and mid gridbounce back boundary condition is implemented on the solid walls In addition momentum equation is derived from the lattice Boltzmann equation for non Newtonianfluids Lattice Boltzmann simulations of five non Newtonian models are presented and incases which analytic solution exists analytic solutions are compared with numericalresults Predicted velocity profiles by the non Newtonian LBM for a channel flow have anexcellent agreement with those of exact solutions presenting the capability of the LBmethod for the non Newtonian fluid flow simulation Finally the procedure of parallelprogramming using LBM is explained and Parallel Distribution toolbox of Matlab softwareis introduced
