The discussion centers on the application of Poiseuille's law in understanding friction force in laminar flow, specifically in biological contexts such as blood flow. It establishes that the only friction in Poiseuille flow arises from fluid viscosity, and equilibrium is achieved when the viscous friction force at the wall equals the pressure drop force along the tube. The conversation highlights the complexities of modeling blood flow due to its non-Newtonian properties, particularly shear thinning, which complicates calculations compared to standard fluid mechanics.
PREREQUISITESStudents and professionals in biomedical engineering, fluid mechanics researchers, and healthcare practitioners interested in the dynamics of blood flow and its physiological implications.
An equilibrium will be attained.notorious said:If the friction force created is smaller than the pressure difference in the vessel, shouldn't the blood accelerate? Or if the friction force is large, shouldn't the blood speed gradually decrease?
It is pretty standard in physics for biology courses to teach all the fluid mechanics as if it applies perfectly to veins.erobz said:Flow problems with blood would be a challenge? Blood is Non-Newtonian - Shear Thinning. I've never tried to do any calculations with it though, so maybe I'm missing boat.
