CFD – Fluid Dynamics Equations Dr. GUVEN Aerospace Engineer (P.hD)

Flow Properties There are certain flow properties inherent in any fluid. These include 1) Viscosity (Friction) 2) Temperature 3) Density 4) Pressure 5) Reynolds Number

Flow Types Steady Flow (Independent t) Unsteady Flow (random delta t change) Uniform Flow (all velocity vectors identical) Non uniform Flow Rotational Flow Non rotational flow Viscous flow Inviscid flow Compressible flow Incompressible flow Laminar Flow Turbulent Flow
