On the durability of surgical masks after simulated handling and wear

Jian Wang, Véronique Michaud, Vincent Marc Varanges, Baris Çaglar, Yann Albert Gérard Lebaupin, René M. Rossi

After the spread of COVID-19, surgical masks became highly recommended to the public. They tend to be handled and used multiple times, which may impact their performance. To evaluate this risk, surgical masks of Type IIR were submitted to four simulated tr ...

Torque Computation With the Isogeometric Mortar Method for the Simulation of Electric Machines

Bernard Kapidani, Rafael Vazquez Hernandez

In this work, isogeometric mortaring is used for the simulation of a six-pole permanent magnet synchronous machine. Isogeometric mortaring is especially well suited for the efficient computation of rotating electric machines, as it allows for an exact geom ...

Experimental Investigation of a Small-Scale Organic Rankine Cycle Turbo-Generator Supported on Gas-Lubricated Bearings

Jürg Alexander Schiffmann, Kévin Rosset

Waste heat recovery (WHR) is expected to contribute to reducing CO2 emissions from trucks. Organic Rankine cycle (ORC) systems show the highest potential for this application, but still lack efficient small-scale expansion devices, in practice. A novel tur ...

Novel Optimized Shape and Topology for Slotless Windings in BLDC Machines

Yves Perriard, Douglas Martins Araujo, Adrien Jean-Michel Thabuis, Guillaume Paul-André Burnand

Slotless windings are commonly used in small size high-speed electrical brushless dc machines. Unlike slotted windings, forced to follow the direction of slots, slotless windings can be freely arranged in the airgap. This represents several opportunities f ...

Effect of voltage source converters with electrochemical storage systems on dynamics of reduced-inertia bulk power grids

Mario Paolone, Fabrizio Sossan, Yihui Zuo

A major concern associated to the massive connection of distributed energy resources is the increasing share of power electronic interfaces resulting in the global inertia reduction of power systems. The recent literature advocated the use of voltage sourc ...

Topology Optimization for Coils of Electric Machine with Level-set Method

Yves Perriard, Adrien Jean-Michel Thabuis, Xiaotao Ren

This work studies the level-set based topology optimization for the optimal layout of winding in electric motor. The functional to optimize is to maximize the torque in the air-gap. The coil domain is initiated by a level set function. The time evolutionar ...

Variable speed operation of centrifugal pumps running as turbines. Experimental investigation

François Avellan, João Nuno Gomes Borga Delgado

Pumps running as turbines are pointed out as a cost-effective solution for energy recovery in pressurised water supply systems. However, these hydraulic machines feature low efﬁciency under variable discharge operation due to the lack of an inlet ﬂow contr ...
