Computational Design and Optimization of Supersonic Intakes

This book offers a unique perspective on the intersection of supersonic intake design, formal optimization methods, and the use of computational fluid dynamics (CFD) for evaluating the performance of intakes. Details of the meta-model and optimization scheme, as well the CFD solvers used at each stage of the optimization process, are presented. Additionally, for a balanced perspective, a separate chapter presents a faster, lower-fidelity alternative to RANS computation, complemented by its illustrative application to hypersonic intakes. Key Features: Discusses multi-objective design of supersonic intakes using formal optimization tools such as Kriging/MOGA. Leverages advancement in CFD methods and optimization techniques for practical supersonic intake design. Covers reduced-order analysis of supersonic intake. Focuses on the intricate aspects of cowl design and throat shaping. Presents conical intake design with geometric constraints and TPR-drag trade-offs This book is aimed at graduate students, researchers, and professionals in aircraft propulsion, intake design, and aerospace engineering.
