Question

Use the Cartesian Navier–Stokes equations to approximate the flow through the left ventricle during peak systole. Assume that the gravitational effects on the flow are negligible and that the opening orifice for blood to flow through is 25 mm (aorta). The width of the left ventricle can be approximated as 2 cm and the total length from the apex of the heart to the aortic valve of 4 cm. Determine the maximum velocity at both the aorta and within the ventricle. Blood viscosity is 3.5 cP assume that the pressure gradient across this flow is −1 mmHg/cm.
