ABSTRACT
In order to perform efficient and cost-effective boundary layer flow analysis, this chapter provides readers with computational methods and design ideas. In the boundary layer, an extremely thin region immediately adjacent to the solid surface, the fluid velocity transitions from zero at the surface to the freestream velocity of the approaching flow. The Reynolds number is crucial to aerodynamic design. When constructing aircraft wings and airfoils, engineers must consider its effect. For example, wings are designed to sustain laminar flow as long as possible to minimise skin friction drag. Airfoil and wing geometry that delay turbulent flow may be chosen. In aerospace engineering, mathematical modelling of boundary layers is crucial for understanding and analyzing fluid flow near solid surfaces. In the pursuit of more comprehensive solutions, multidisciplinary approaches will integrate knowledge from fluid dynamics, materials science, and control theory.
