The present work illustrates a difficulty with the level-set method to accurately capture the curvature of interfaces in regions that are of equal distance to two or more interfaces. Such regions are characterized by kinks in the level-set function where the derivative is discontinuous. Thus the...

Time-resolved laser-induced incandescence (LII) signal of soot in an ethylene laminar diffusion flame was measured with varying laser pulse durations in the range 50–600 ns. This study presents original results since the majority of LII studies reported are based on 7–10-ns pulse duration. The LII...

A heat pump drying system of an industrial sized batch tunnel drier with 40 tons of clipfish was analyzed in a dynamic process simulation. The convective drying dynamics were determined experimentally and used to verify a drying model for clipfish. The drying process was simulated in a 250 kW heat...

The technology and the operational patterns of HVDC links are changing, and therefore, the type test requirements for mass-impregnated non-draining HVDC cables are currently being reconsidered. A CIGRÉ working group is preparing a revised type test recommendation. Measurements and numerical...

This paper presents results from experimental tests intended to assess the validity of linear damage superposition using Miner’s rule for IGBT power modules. Such validity is crucial, for example, when applying Miner's rule in combination with power cycling lifetime models for estimating converter...

In this paper, backstepping is applied as a first step of modulation control in the abc reference frame for modular multilevel converters (MMCs). In the second step, reduced indirect FCS-MPC is applied where the number of inserted modules are allowed to change...
