Geurts (U. of Twente) explains direct and large-eddy simulations of turbulent flow, focusing on how to capture the primary features of unsteady flow through computation rather than on a complete statistical modeling. The approach incorporates elements of numerical and mathematical-physical modeling. He speaks primarily to applied scientists and engineers involved in developing and applying computational fluid dynamics for turbulent flows, but thinks his account could also serve as an introduction for academic researchers and graduate students in engineering, applied mathematics, or physics.
