OBJECTIVES We sought to determine, using serial echocardiography, the hydrodynamic mechanisms involved in the occurrence of hemolysis after mitral valve repair. BACKGROUND Recently, fluid dynamic simulation models have identified distinct patterns of mitral regurgitant flow disturbances in patients with mitral prosthetic hemolysis that were associated with high shear stress and may therefore ...

We investigate the coefficients generated by expressing the falling factorial (xy) as a linear combination of falling factorial products xy for l, m = 1, . . . , k. Algebraic and combinatoric properties are discussed, some in relation to Stirling numbers.

Abstract To calculate the dynamics and structure of flows, a system fundamental equations fluid mechanics with state for Gibbs potential density an inhomogeneous medium is applied. The complete solution describes ligaments, waves, vortices, jets, wakes, other types flows. Calculations flow patterns around obstacles are consistent experiment. Observations processes merging freely falling drop ta...

Abstract Submerged and impinging jets with harmonic perturbations added to the inlet velocity profile nozzle vibrations are simulated numerically at different Reynolds (Re) Strouhal (St) numbers by solving Navier–Stokes equations. The effects of Re, St forcing amplitudes on flow behavior jet splitting phenomena studied.
