Small innovations, big impact: Leveraging CFD to drive global change

Foiling, once the exclusive domain of elite sailing and Olympic feats, is now making waves in the motorboat industry, redefining the concepts of speed, efficiency and comfort on the water.

Although foiling is not a new idea, recent advancements in computational fluid dynamics (CFD) and innovative composite materials have unlocked its full potential. These technologies have demystified the complex hydrodynamics of foiling, enabling precise control and introducing an era where motorboats can effortlessly ‘fly’ across the waves with unparalleled smoothness and efficiency.

Hydro-foiling represents the perfect fusion of cutting-edge technology and pure enjoyment—allowing boats to glide across the water with minimal resistance, reducing fuel consumption, and transforming a potentially rough ride into a smooth, almost serene experience.

Leading this revolution is SEAir Solutions, which combines traditional naval architecture with state-of-the-art simulation tools like Siemens’ NX and Simcenter. Their approach goes beyond simply adding foils to boats; it involves creating a comprehensive design and testing ecosystem that optimizes every aspect, from the hull to the foil. Through meticulous use of digital twin representations and extensive real-world trials, SEAir demonstrates how modern engineering can turn ambitious concepts into high-performance realities.

This issue also delves into the transformative power of the digital twin across various industries. We explore how the digital twin is revolutionizing pump design—an often-overlooked device that accounts for nearly ten percent of the world's electricity use. Even small improvements in pump efficiency can have a significant global impact. Additionally, we examine their role in the operation of large hydroelectric power stations in Norway. Despite the scale differences, these applications share a common goal: leveraging the digital twin to enhance efficiency, reliability, and sustainability.

In this edition, we also provide insights into advanced simulations and digital twin technologies. We take you inside the world’s quietest wind tunnel, explore the critical role of fluid dynamics, and assess the impact of AI on engineering workflows. From vehicle durability testing to breakthroughs in in-car audio and in-flight connectivity, this issue offers a comprehensive view of the technologies shaping the future of engineering.

Enjoy the insights,
