Analytical surface-function (ASF) methods for surface boundary conditions of turbulent flows are reviewed.

Analytical surface-function (ASF) methods for surface boundary conditions of turbulent flows are reviewed. Since the methods integrate transport equations of momentum and scalars over the control volumes adjacent to surfaces with some simplifications, it is suitable to consider complex surface-flow physics into the surface-function formula. In this sense, in the present talk, the scheme is named the ASF whilst the ASF for wall boundaries is called the analytical wall-function (AWF). This recently emerged ASF scheme has shown its successful potential to treat turbulent flows and scalar transport near solid smooth, rough and permeable walls. High Prandtl or Schmidt number scalar transport near walls or free surfaces are also well handled by the concept of the ASF.
