Abstract EN
Blood flow characteristics in the normal left ventricle are studied by using the magnetic resonance imaging, the Navier-Stokes equations, and the work-energy equation.
Vortices produced during the mitral valve opening and closing are modeled in a two-dimensional analysis and correlated with temporal variations of the Reynolds number and pressure drop.
Low shear stress and net pressures on the mitral valve are obtained for flow acceleration and deceleration.
Bernoulli energy flux delivered to blood from ventricular dilation is practically balanced by the energy influx and the rate change of kinetic energy in the ventricle.
The rates of work done by shear and energy dissipation are small.
The dynamic and energy characteristics of the 2D results are comparable to those of a 3D model.
