Aerodynamic Study on Low Reynolds Number Aerofoil

Abstract

Low Reynolds number refers to a specific range of values of the dimensionless parameter known as the Reynolds number (Re) in fluid dynamics. The Reynolds number is a critical factor used to characterize and predict fluid flow behaviour around objects or within fluid systems. Low Reynolds numbers (typically Re < 2000), laminar flow prevails, where fluid particles move in smooth, orderly layers with minimal mixing or turbulence. Low Reynolds number aerodynamics is a focal point of interest, especially for micro air vehicles (MAVs), drones, and small-scale aircraft. Understanding the nuanced aerodynamic performance of aerofoils and wings in this regime is pivotal for designing efficient and controllable flight systems, ushe ring in innovations in the field of aviation. The unique characteristics of low Reynolds number flow to advance technology, science, and our understanding of fluid dynamics.
