A self-propagating, free-vortex pair is mapped into an infinite strip, and a semi-infinite strip. The strip geometries are plane two-dimensional approximations of the open and closed aortic valve regions. Vortex trajectories, velocity fields and pres

A finite-difference numerical method for the solution of the unsteady flow of a viscous incompressible fluid through axisymmetric circular ducts of variable axial geometry is developed and applied to the flow in a spherical-cavity geometry approximat

The Magnus force on a rotating body traveling through a fluid is partly responsible for ballistic missile and rifle shell inaccuracies and dispersion and for the strange deviational behavior of such spherical missiles as golfballs and baseballs. A gr

The experimental test results for operating a hydraulic turbomachine in every possible manner (noncavitating) are presented for a representative single-stage axial-flow and mixed-flow pump. A comparison is made among the three basic types of machine,

Turbulent drag reductions on the order of 50% were obtained for pipe flow of submicron, rod-like particle suspensions at weight concentrations of less than 0.5%. Wall Reynolds numbers as high as 40,000 were obtained for the suspensions. The suspended

A numerical analysis is carried out for oscillatory flow of a viscous incompressible fluid through thin-walled elastic tubes with small curvature. A wave propagation analysis for sinusoidal input pressure disturbance yields a resulting asymmetrical f

Circulatory system characteristics are considered with respect to specifying model design parameters for simulators and pulse duplicators. The requirements are investigated to determine what characteristics and parameters are important in design and

The in vitro steady and pulsatile flow results of tests of a series of valves are reported. Fifteen mechanical and two tissue valves from 23 mm to 27 mm nominal size from six manufacturers, plus two prototype experimental valves, were tested in the a

Steady-state pressure-drop vs flow-rate measurements on prosthetic valves have been shown to correlate well with mean cyclic pressure drops vs RMS flow rate during systolic ejection from pulsatile flow data. The use of steady-state data is therefore
