Paragraph starter
The preliminary design of turbomachinery, such as automotive turbines, often involves balancing competing factors like aerodynamic efficiency and low inertia. Research by Cox, Fischer, and Casey (2010) highlights the effectiveness of employing a quasi-3D throughflow modelling approach coupled with an optimization algorithm. This method demonstrated the potential to significantly increase turbine efficiency or reduce inertia compared to traditional empirical design strategies, suggesting that integrating such modelling techniques early in the design process can lead to more optimized and responsive components.
