Similarity Analysis of Favorable Pressure Gradient Turbulent Boundary Layers with Eventual Quasilaminarization
Physics of Fluids
Using similarity analysis, the scales and similarity constraints for a favorable pressure gradient (FPG) turbulent boundary layer with eventual quasilaminarization are obtained. In order to achieve equilibrium in the boundary layer, the pressure parameter Λ must be a constant; thus, a power relation between the boundary layer thickness δ and the free-stream velocity U∞ exists. Consequently, the power is given by the pressure parameter Λ as δ∼U∞− 1/Λ. Through an analysis using the pressure parameter, two quadrants are found...
