Boundary Layer Thickness of Laminar Sublayer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Boundary Layer Thickness = (11.6*Kinematic Viscosity)/(Shear Velocity)
δ = (11.6*v')/(V_')
This formula uses 3 Variables

Variables Used

Boundary Layer Thickness - (Measured in Meter) - Boundary Layer Thickness is the distance normal to the wall to a point where the flow velocity has essentially reached the 'asymptotic' velocity.
Kinematic Viscosity - (Measured in Square Meter per Second) - The Kinematic Viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid.
Shear Velocity - (Measured in Meter per Second) - Shear velocity, also called friction velocity, is a form by which a shear stress may be re-written in units of velocity.

STEP 1: Convert Input(s) to Base Unit

Kinematic Viscosity: 7.25 Stokes --> 0.000725 Square Meter per Second (Check conversion here)
Shear Velocity: 6 Meter per Second --> 6 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

δ = (11.6*v')/(V_') --> (11.6*0.000725)/(6)

Evaluating ... ...

Boundary Layer Thickness = (11.6*Kinematic Viscosity)/(Shear Velocity)
δ = (11.6*v')/(V_')

How is boundary layer thickness defined?

We define the thickness of the boundary layer as the distance from the wall to the point where the velocity is 99% of the “free stream” velocity.

What affects thickness of boundary layer?

The thermal boundary layer thickness is altered due to the presence of flow during boiling in microchannels. If the flow rates are high, the thermal boundary layer thickness is reduced.
