Viscosity — Shear Rate, Shear Stress and Newton’s Law
Learn about fluid viscosity, shear stress, shear rate, and Newton’s law of viscosity with a Couette flow simulation. Applications in Reynolds number and IYPT snail ball.
Reynolds Number — From Laminar Flow to Turbulence
What is the Reynolds number? Definition, physical meaning, worked examples (blood, air, bacteria), connection to IYPT problems, and derivation from Navier-Stokes. With dynamic similarity and drag crisis explained.
