Assessment of a double-MRT pseudopotential lattice Boltzmann model for multiphase flow and heat transfer simulations
(Elsevier, 2021-01)
In this work, a double-MRT lattice Boltzmann (LB) model for thermal multiphase flow is presented and analyzed. The model is based on a pseudopotential scheme, and introduces a second equation with a non-diagonal relaxation ...
Optimized Switching Sequence for Multiphase Power Converters Under Inductance Mismatch
(Institute of Electrical and Electronics Engineers, 2017-03)
Multiphase power converters allow to reduce semiconductor stress and to improve total ripple characteristics, when compared to a single-phase converter. Semiconductor stress is reduced by dividing the total current among ...
