Comparison of Steady and Unsteady Secondary Flows in a Turbine Stator Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of periodic rotor wakes on the secondary flow structure in a turbine stator cascade was investigated. A mechanism simulated the wakes shed from rotor blades by passing cylindrical ...
Calculation of Velocity Profiles in Drag-Reducing Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A calculation procedure for predicting mean velocity profiles in drag-reducing flows is presented. The procedure is based upon the eddy diffusivity model of Cess and it requires only pressure ...
Influence of Cardiac Flow Rate on Turbulent Shear Stress from a Prosthetic Heart Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elevated turbulent shear stresses associated with sufficient exposure times are potentially damaging to blood constituents. Since these conditions can be induced by mechanical heart valves, the ...
Effect of Tilting Disk, Heart Valve Orientation on Flow Through a Curved Aortic Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of tilting disk valve orientation on pulsatile flow through a curved tube model of the human aorta was studied. Simultaneous, two-component laser Doppler velocimeter measurements ...
Two-Component Laser Velocimeter Measurements Downstream of Heart Valve Prostheses in Pulsatile Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elevated turbulent shear stresses resulting from disturbed blood flow through prosthetic heart valves can cause damage to red blood cells and platelets. The purpose of this study was to measure ...
