Hairpin winding technology, combined with direct oil jet impingement cooling, is a viable solution known to increase volumetric power density and efficiency in the next generation of traction motors. However, the coolant fluid interaction with the complex winding geometry has not yet been fully examined; specifically, with the use of high-fidelity CFD simulations. Thus, the present work investigates the radial and axial oil impinging jets in a hairpin winding motor using multi-phase simulation. The study first analyses power losses and temperature distribution of the motor under the Worldwide Harmonised Light Vehicle Test Procedure (WLTP). Next, the performance of axial and radial jet impingement is numerically analysed by considering the fluid flow. Finally, the two configurations are compared in terms of their oil film formation rate. The results indicate that the maximum power losses observed in typical driving conditions are considerably lower than the maximum losses predicted for the complete operational region of the motor. Moreover, the axial impinging jet shows a higher oil film formation rate compared to a radial jet impingement configuration within the examined conditions.

“…A library to estimate the operational range of two commercial EVs, using the Modelica Language was used. Detailed information about the mathematical modelling, vehicle's parameters and model limitations are presented in [13]. Models were validated using the New European Driving Cycle (NEDC) and the range was compared with manufacturer's data.…”

“…A lot of models that have been created using the OOM paradigm can be found on the literature. To cite just a few recent works from several fields, there are examples of mechanical systems [16][17][18], electrical systems [19][20][21], thermal systems [22][23][24][25], energy systems [26][27][28][29] and processes [30,31]. This clearly shows that OOM is a very useful methodology for modelling multidisciplinary complex systems.…”

Software Tool for Acausal Physical Modelling and Simulation

Modelling and simulation are key tools for analysis and design of systems and processes from almost any scientific or engineering discipline. Models of complex systems are typically built on acausal Differential-Algebraic Equations (DAE) and discrete events using Object-Oriented Modelling (OOM) languages, and some of their key concepts can be explained as symmetries. To obtain a computer executable version from the original model, several algorithms, based on bipartite symmetric graphs, must be applied for automatic equation generation, removing alias equations, computational causality assignment, equation sorting, discrete-event processing or index reduction. In this paper, an open source tool according to OOM paradigm and developed in MATLAB is introduced. It implements such algorithms adding an educational perspective about how they work, since the step by step results obtained after processing the model equations can be shown. The tool also allows to create models using its own OOM language and to simulate the final executable equation set. It was used by students in a modelling and simulation course of the Automatic Control and Industrial Electronics Engineering degree, showing a significant improvement in their understanding and learning of the abovementioned topics after their assessment.
