It is also categorized as half-equation model, because it essentially solves for an Ordinary Differential Equation (ODE) rather than a Partial Differential Equation (PDE) (Normally for popular turbulence models transport equations are solved which are PDE's). This model solves for a transport equation for the maximum shear stress. It was not developed to be a universal model, rather to solve only for turbulent boundary layer flows with strong adverse pressure gradient.
