1.	The layer with viscous and turbulent stresses in equal magnitude is called _____________(a) Viscous sub-layer(b) Log-law layer(c) Buffer layer(d) Velocity-defect layerI got this question in semester exam.Enquiry is from Turbulent Boundary Layer topic in chapter Turbulence Modelling of Computational Fluid Dynamics
Answer» The correct option is (c) Buffer layer Explanation: The layer above the linear sub-layer has EQUALLY important TURBULENT and viscous stresses. Neither of these is dominating nor inconsiderable. A layer in this AREA where both the viscous and turbulent stresses are of equal MAGNITUDE is CALLED the buffer layer.
