This book contains the proceedings of the Cambridge Unsteady Flow Symposium, held on 4-5 March 2024 at the University of Cambridge. The book brings together internationally leading experts in computational fluid dynamics (CFD) and promotes discussions on numerical methods for unsteady flows. The book covers a wide range of topics related to CFD, including but not limited to, large-eddy simulations, unsteady flows in aerospace, high order methods, and mesh generation.
