About

Dr. Chunning Ji is a leading researcher in the field of fluid dynamics, with a primary focus on unsteady aerodynamics and bio-inspired propulsion. His work centers on understanding the complex flow physics of oscillating foils, which are critical for the design of efficient underwater vehicles and energy-harvesting devices. Dr. Ji’s major contributions include a systematic investigation of the drag–thrust transition and wake structures of pitching foils, particularly those undergoing asymmetric and combined fast-slow oscillations. His 2021 study on the drag-thrust transition, which has garnered 35 citations, provides a foundational understanding of how foil kinematics influence propulsive efficiency. Additionally, his work on the flow map of foils undergoing combined fast and slow pitching (15 citations) introduced a novel variable to characterize the pitching time fraction, offering a new framework for analyzing locomotion. These studies have significantly advanced the theoretical and practical knowledge of vortex dynamics and thrust generation. Dr. Ji’s research is highly regarded for its clarity and impact, making him a key figure in the study of oscillating foil hydrodynamics and a valuable resource for students and researchers exploring unsteady flow phenomena.
