The present study is established on a simulation using CFD analysis in COMSOL. Blood acted as the base fluid with this simulation. taken flow been modeled incompressible, unsteady, laminar and Newtonian fluid, which appropriate at high rates of shear. characteristic blood studied order to determine pressure, velocity temperature impact caused by an abdominal aortic aneurysm (AAA). This work employs nanoparticles Iron Oxide (Fe3O4) type. technique utilized evaluate equations mass, momentum, energy. COMSOL software generate normal element sized mesh. findings demonstrate that alters through aneurysmal part aorta, higher diseased segment, increases before after region. For heat transfer feature, reference general inward flux 293.15K 800W/m2. altered blood's physical properties, including conductivity, dynamic viscosity, specific heat, density. inclusion managed prevent overheating because have significant thermal conductivity. These will be extremely beneficial treatment aneurysm.
