High power density is an important requirement for traction motor drives as transportation systems continue their electrification trends. Increasing requires a system-level approach addressing all inverter components; particularly, modules, thermal management system, and dc-link capacitor bank. This paper focuses on designing distributed bank using multi-layer series-connected ceramic capacitors (MLSCs) which have higher operating temperature, lower ESL volume than film capacitors. The...

The Eulerian–Eulerian Large-eddy simulations (LES) of gas–liquid two-phase flow in a cylindrical bubble column reactor have been conducted. When considering the turbulent eddy viscosity LES, apart from well-accepted contributions shear turbulence and induced (BIT), effect interaction between entrained bubbles eddies with similar length scale to sub-grid (SGS) cannot be neglected. With consideration response on stresses, modified SGS model, which incorporates Stokes number, St, was proposed....

Abstract Through Euler/Euler large eddy simulation (LES) modeling, it is demonstrated that turbulent dispersion of bubbles can effectively indicate the impact eddies on bubble dynamics, i.e., oscillation behavior.

It has now been recognised that the turbulent dispersion force plays an important role in interphase momentum transfer. As eddies surrounding of bubbles interact strongly with bubbly flow, bubble trajectories and oscillation take place accordingly as consequence continuous deformation surfaces.

The SGS-filtered velocity fluctuations of the liquid phase can be envisaged as turbulent eddies that act on surface bubbles, consequently causing bubble dispersion. As a result, so-called dispersion force and added mass stress are usually considered non-dominant forces in interfacial momentum transfer but they have been overlooked many Euler/Euler modelling column bubbly flows. present study will demonstrate through LES such bubbles effectively indicate effect dynamics, i.e. oscillation...
