In many scientific and engineering applications of complex
flows, computational efficiency is of paramount importance. Thus, model
reduction techniques are frequently used. To achieve a balance between the
low computational cost required by a reduced-order model and the complexity
of the target turbulent flows, appropriate closure modeling strategies need
to be employed. In this talk, we present reduced-order modeling strategies
synthesizing ideas originating from proper orthogonal decomposition and
large eddy simulation, develop rigorous error estimates and design
efficient algorithms for the new reduced-order models.
