 Biological hydraulics , or biofluid mechanics, is that the study of both gas and liquid fluid flows in or around biological organisms. An often studied liquid biofluid problem is that of blood flow within the human circulatory system . Under certain mathematical circumstances, blood flow are often modeled by the Navier–Stokes equations. in vivo blood is assumed to be an incompressible Newtonian fluid. However, this assumption fails when considering forward flow within arterioles. At the microscopic scale, the consequences of individual red blood cells become significant, and blood can not be modeled as a continuum. When the diameter of the vessel is simply slightly larger than the diameter of the red blood corpuscle the Fahraeus–Lindquist effect occurs and there's a decrease in wall shear stress. However, because the diameter of the vessel decreases further, the red blood cells need to squeeze through the vessel and sometimes can only pass during a file . during this case, the inverse Fahraeus–Lindquist effect occurs and therefore the wall shear stress increases. When two surfaces rub against one another , the effect of that rubbing on either surface will depend upon friction, wear and lubrication at the purpose of contact. for instance , the femoral and tibial components of knee implants routinely rub against one another during daily activity like walking or stair climbing. If the performance of the tibial component must be analyzed, the principles of contact mechanics and tribology are wont to determine the wear and tear performance of the implant and therefore the lubrication effects of synovia .
