"Fluid" is an amazing substance that we often encounter in our lives. It lacks a fixed shape and can change at any time, which has attracted the attention of many physicists and mathematicians who dedicate themselves to the study of "Fluid Mechanics." This field aims to explore the states and laws of fluids in motion.
In a recent article in Wen Wei Po, Prof. Tong YANG, a member of the Hong Kong Academy of Sciences and Chair Professor of Mathematical Science in the Department of Applied Mathematics at PolyU, introduces the scientific concept of "fluid" and provides a historical overview of the study of "Fluid Mechanics." He explores how physicists and mathematicians analyse the "Boundary layer theory" (BL theory) by using the Reynolds number, which is an important parameter in aerodynamics to address unsolved mathematical problems associated with it.
Prof. YANG’s scientific research focuses on Conservation laws, Boltzmann equation and Boundary layer theories. Earlier, Prof Yang’s joint research project, titled “Mathematical theory of compressible Navier-Stokes equations and related models”, was bestowed the First-Class Award in Natural Science at the Higher Education Outstanding Scientific Research Output Award (Science and Technology) 2022, to recognise his outstanding scientific research contributions.
