In this paper the authors present a derivation of back-scatter rotational Large Eddy Simulation model, which is extension Baldwin & Lomax model to non-equilibrium problems. The particularly designed mathematically describe fluid filling domain with solid walls and consequently differential operators appearing in smoothing terms are degenerate at boundary. After prove some mathematical propertie...

This article presents the converter circuit analysis, mathematical modeling followed by deriving its average state space equations. The model so obtained is simulated in MATLAB open loop and closed configuration changes output are observed. Specifically, Buck & Boost converters with without controller at steady study of their transient responses to changing inputs a design implementation on...
