The turbulence of the flow is crudely represented by a prescribed constant turbulent viscosity within the fluid, together with a logarithmic law of the wall for skin friction. The lower (south) boundary of the flow domain, representing the road surface, is modelled as a moving wall. An impression of the geometry can be gained by examining the following sketch. | ______________ |______ |**************| |******| ^ __|**************| ^ |******| | |*****************| | |******| y| |*****************| y| |******| | ~**~~~~~~~~~~~~~**~ | |~~~~** ** ** | ** ------------------------------------------- z----> x---> ENDDIS ************************************************************ Group 1.
