Recent development of aerodynamic design methodologies

Computational Fluid Dynamics (CFD) has advanced significantly over the past two decades, becoming an essential analytical tool for both fundamental and practical fluid dynamics research. Analyzing flow fields enhances researchers' understanding of flow features and indirectly aids in the design of new aircraft and spacecraft. However, effective design methodologies are crucial for actual development, as they streamline the design process and can greatly shorten design cycles. Despite numerous publications on the subject, many proposed methods have remained unused due to immature research and limited computing capabilities. With the advent of high-speed computers, the time is ripe for practical application of these methods. There is a notable increase in interest surrounding aerodynamic inverse design and optimization techniques, not only within aerospace industries but also in various sectors requiring fluid dynamic design. This trend highlights the pressing engineering need for optimal aerodynamic shape design methodologies. Consequently, it is an opportune moment to compile insights from leading researchers in this field, allowing them to share their research efforts and discuss their findings in relation to broader advancements.
