Relationship between viscosity and length
WebJun 1, 2012 · Moreover, the same can also be concluded from the basic rheological (viscosity) relations: (3) τ = η d v x d y = ρ ν d v x d y, where τ is the shear stress between the lubricant layers, η is the dynamic viscosity, ρ is the density, ν is the kinematic viscosity and dv x /dy is the gradient of velocity along the lubricating film thickness. WebOct 17, 2012 · Turbulent Boundary condition, viscosity ratio and length scale. I am simulating a 2D inclined flat plate with an angle of attack of 70º. My domain goes 10H upstream (say H is the plate height, H=9.3 m), 20H downstream, 10H up and 10H down. Velocity at the inlet is 10 m/s. I am using k-epsilon model with TI=10%.
