Vortex dynamics and heat transfer in a viscous incompressible 
fluid flow past shallow and deep trenches on a plane wall are studied 
methodically within the framework of the multiblock approach to solution 
of steady-state Reynolds equations closed by the Menter and Spalart-Allmaras 
turbulence models and the energy equation.
