Designing an Efficient EV for the Shell Triple 10 Challenge

As battery electric vehicles (BEVs) continue to evolve, automotive manufacturers face a fundamental engineering challenge: how to improve range, charging performance and sustainability without relying solely on larger battery packs. For many years, increasing battery capacity provided a straightforward route to extending vehicle range. However, larger batteries introduce additional mass, higher material consumption and increased […]
Validating Marine Propeller Performance with HELYX CFD

In naval architecture and marine engineering, open-water curves, such as the thrust, torque and efficiency are the primary hydrodynamic input to propeller and propulsion design. Capturing such quantities accurately through CFD modelling helps engineers take design decisions. This article takes part of our ongoing HELYX Validation and Verification series, comparing the CFD results against the […]
