Abstract: We show that the mean wall-shear stresses in wall-modeled large-eddy simulations (WMLES) of high-speed flows can be off by up to $$\approx 100\%$$≈100% with respect to a DNS benchmark when using the van-Driest-based damping function,… read more here.

Abstract: This study presents a model predictive control (MPC) with active damping function for current-source rectifiers (CSRs). Since optimal modulating vector selection process of MPC leads to spread harmonic distribution in pulse-width-modulated (PWM) waveform, inductor-capacitor (LC)… read more here.
