Abstract
This research article delves into a systematic comparative analysis focusing on the efficiency of fluid dynamic devices and highlights the notable differences and complementarities of experimental and computational methods. Historically, fluid dynamics as a research area has been heavily focused on experimental techniques. Instruments such as wind tunnels, water tunnels, and a variety of measuring devices formed the cornerstone of research, allowing scientists and engineers to directly observe and measure the behavior of fluids. With technological advances, Computational Fluid Dynamics (CFD) has become a powerful tool that offers the ability to simulate complex fluid flows, providing insights that were previously difficult or impossible to obtain experimentally. While experimental methods provide real-time, tangible results that can be visualized and measured, CFD stands out for its ability to provide comprehensive data sets that allow researchers to conduct in-depth analyzes and conduct large-scale parametric studies without the need for physical setups. In current fluid dynamics research there is a clear trend towards integrating both methods. Computer simulations supported by CFD can play a crucial role in the design and optimization of experimental setups. Conversely, real experimental results serve as a crucial benchmark to validate and refine the computational models generated by CFD. This combined approach not only expands the depth and breadth of research, but also paves the way for the design and realization of fluid dynamic devices that are significantly more efficient and effective.
