This paper describes the torque production capabilities of electrical machines with planar windings and presents an automated procedure for coils conductors' arrangement. The procedure has been applied on an ironless axial flux slotless permanent magnet machines having stator windings realized using printed circuit board (PCB) coils. An optimization(More)
This paper presents an automated procedure for coils conductors' arrangement. The procedure has been applied to slotless permanent magnet machines having planar magnetic stator windings, such as printed circuit board (PCB) coils. The proposed method is driven by optimization techniques whose goal is to find a proper arrangement of PCB traces, which make up(More)
This paper illustrates some results about the experimental characterization of current carrying capacity (CCC) of printed circuit board (PCB) stator coils. Thermometric tests have been carried out with both DC and AC power supply, in order to evaluate the relationship between flowing current and coils temperature rise and quantify with experiments the(More)
This paper is concerned with the development of NPHASE, a next generation computational fluid dynamics (CFD) computer code to simulate multicom-ponent multiphase flows of interest in research and industry. The NPHASE code is focused on developing a robust flow solver that is designed from the beginning to handle the complex interactions between numerics and(More)
A three-dimensional multi-field Coupled Phasic Exchange (CPE) algorithm, for the prediction of general two-phase flows is presented. The algorithm is applicable to an arbitrary number of fields a four-field construct is adopted here. Ensemble averaged transport equations for mass, momentum, energy and turbulence transport are solved for each field(More)
