Journal ArticleDOI
Turbulent stresses in the region of aortic and pulmonary valves.
TL;DR: Because the Reynolds normal stresses in the presence of the severely stenotic and regurgitant valves were comparable in vitro and in patients, it is likely that the Reynolds shear stress in patients is also comparable to values measured in vitro.
Journal ArticleDOI
Patterns of Flow in the Left Coronary Artery
TL;DR: Observations suggest that helical flows may be characteristic features of flow in the left coronary artery; whereas turbulence may not be a feature of this flow field.
Journal ArticleDOI
Velocity profiles in symmetrically branched tubes simulating the aortic bifurcation
F. J. Walburn,Paul D. Stein +1 more
TL;DR: In this article, the authors measured velocity profiles in a symmetrically branched tube with an area ratio (0.8) and angle of branching (70°) that were comparable to the bifurcation of the human descending aorta.
Journal ArticleDOI
An experimental evaluation of the use of an ensemble average for the calculation of turbulence in pulsatile flow
TL;DR: It is suggested that ensemble averaging may not be appropriate for the calculation of turbulence, particularly in patients, because of the variations in beat-to-beat variations of the nonfluctuating velocity.
