BioFluid.pdfReynolds number is an index of the degree of turbulence based on the balance of inertia and viscosity. It is calculated by (ρ * v * L) / μ, which is: (density of the fluid*the characteristic velocity of the fluid flow*the characteristic length)/the dynamic viscosity of the fluid. As the inertia becomes larger compared to the viscosity, the Reynolds number becomes larger and the flow is more turbulent. The Reynolds number can be used to determine whether the entire flow field is turbulent or laminar. Reynolds number will increase during systole, yet decrease down to zero during diastole. https://B2n.ir/hh3655☑ @Biomekanics
