Abstract: Computational hemodynamics (CHD) is a promising engineering technique that has allowed doctors to learn a lot about patients’ conditions in various diseases such as cardiovascular disease (CVD) and even surgery. In industrialized countries, hypertension is becoming a widespread public health issue, resulting in death in extreme cases. A successful method for investigating hypertension in both diastolic and systolic conditions is to use the finite volume method (FVM) to incorporate velocity and pressure. Due to the use of Magnetic Resonance Image (MRI) and Digital Imaging and Communications in Medicine (DICOM), the 3D geometry has an acceptable accuracy, and the geometry has been created based thereon. The flow of blood is regarded as steady, lamina, incompressible, and non-Newtonian. Herein, all the age groups have their unique effect on the parameters reported, including Nusselt number and dimensionless numbers, e.g., average wall shear stress (AWSS), temperature, and pressure drop. In such a numerical simulation, all the results revealed that the parameters improved by increasing diastolic and systolic blood pressure. Nevertheless, the patient is recommended to see a doctor urgently in case of a hypertensive situation.
