Blood flow simulations in computational fluid dynamics (CFD) are seen as a very attractive solution for diagnosing diseases. The main objective of this work is to simulate blood flow in healthy arteries. The governing equations for the Sisko model are presented in cylindrical coordinates. The finite volume method is used for the velocity and wall shear stress at healthy arteries. It is observed that the velocity profile increases due to an increase in Sisko fluid parameters and the radius of healthy arteries. With regard to the fact that blood flow in healthy arteries is non-Newtonian, the fluid obeys the Sisko fluid model. We contemplate that due to an increase in Sisko fluid parameters and the radius of healthy arteries, the wall shear stress profile increases and decreases, respectively.
