A data-assimilation method for Reynolds-averaged Navier–Stokes-driven mean flow reconstruction

We present a data-assimilation technique based on a variational formulation and a Lagrange multipliers approach to enforce the Navier–Stokes equations. A general operator (referred to as the measure operator) is defined in order to mathematically describe an experimental measure. The presented metho...
