Weaknesses of the k-ε model with wall functions

Despite the great variety of turbulence modelling options available to the user, the k-ε model joint to Law of the Wall functions, remains the workhorse of the industrial computation. It is therefore of value to catalogue the major weaknesses associated with this model in practical application, and if possible, indicate palliative actions which might be fruitfully considered. These are listed below.
