Meaning and Usage

The term "boundary layer growth" refers to the increase in the thickness of the boundary layer, which is a thin region of fluid (e.g., air or water) in immediate contact with a surface over which it flows. This concept is commonly applied in fields like fluid dynamics, meteorology, and aerodynamics. It is used to describe the behavior of fluid flow near surfaces, where the effects of viscosity become significant.

Frequency of Use: The term is moderately specialized and is often used in scientific literature, making it more prevalent in written contexts, particularly in research papers, textbooks, and technical documents, as opposed to everyday oral speech.
