A New Conceptual Model for Laminar Boundary Layer Flow

Abstract

Computer simulation results indicate that the traditional Blasius laminar flow treatment does not describe the boundary layer flow correctly. The problem is found to be the traditional conceptual model for the boundary layer, it is flawed. The fix is to apply the unbounded and bounded boundary layer concepts introduced in an earlier report. Herein we flesh out the unbounded boundary layer concept applied to laminar flow along a wall. The Blasius model is found to represent the viscous region and approximate analytical solutions are found for the inertial region. The new model is comparable to simulation. The new conceptual models have implications for turbulent flows and wind tunnel experiments.
