“…For zero-equation transition models, Kubacki and Dick [43,44] proposed an algebraic γ transition model that requires no transport equation. Sandhu and Ghosh [45] modified the k-equation of the SST k − ω turbulence model, where k is the turbulent kinetic energy and ω is the specific dissipation rate of k, by (1) multiplying its production and destruction terms by the algebraic γ expression and (2) adding three extra terms (diffusion, source and sink) to account for the effects of transition on the mean flow.…”

The objective of the present work is to propose an extended analytical wall function that is capable of predicting the bypass transition from laminar to turbulent flow. The algebraic γ transition model, the k−ω turbulence model and the analytical wall function are integrated together in this work to detect the transition onset and start the transition process. The present analytical wall function is validated with the experimental data, the Blasius solution and the law of the wall. With this analytical wall function, the transition onset in the skin friction coefficient is detected and the growth rate of transition is properly generated. The predicted mean velocity profiles are found to be in good agreement with the Blasius solution in the laminar flow, the experimental data in the transition zone and the law of the wall in the fully turbulent flow.
