Physiologic blood flow is turbulent

Turbulent Flow over Cars

In this paper the flow behaviour over a number of car bodies is studied. For this purpose the unsteady 2-D incompressible Navier-Stokes equations have been applied. After averaging and nondimensionalizing the equations, the system of equations has been transformed from the Cartesian (x-y) coordinates to a body fitted generalized (-) coordinate. As the flow is incompressible, the density in the ...

Anatomic and physiologic considerations in measurements of myocardial blood flow.

THE CLINICAL importance of ischemic heart disease has provided a powerful stimulus for the development of new and better methods for the study of the coronary circulation. In the animal laboratory, the electromagnetic flowmeter has replaced the rotameter as the standard method of measuring coronary blood flow. Flowmeter probes can be implanted around a dog's coronary artery and utilized to stud...

A Physiologic Model for the Problem of Blood Flow through Diseased Blood Vessels

Received Mar 10, 2016 Revised May 12, 2016 Accepted May 24, 2016 This study focuses on the behavior of blood flow through diseased artery in the presence of porous effects. The laminar, incompressible, fully developed, non-Newtonian in an artery having axially non-symmetric but radially symmetric stenosis is numerically studied. Here blood is represented as Herschel-Bulkley fluid model and flow...
