boundary layer
In fluid dynamics, this term describes a specific physical phenomenon where viscosity slows down the flow of a fluid near a surface. It is a technical term used primarily in aerodynamics, hydrodynamics, and meteorology to explain drag and skin friction. The concept is central to understanding how aircraft wings generate lift and how ships move through water.
When used metaphorically, the term describes a fragile or transitional space where two opposing forces or environments meet. In this context, it suggests a zone of instability or gradual change rather than a sharp, definitive line, emphasizing the process of transition between two distinct states.

We need to calculate the thickness of the boundary layer to optimize the heat transfer.
Turbulence within the boundary layer can significantly increase skin friction drag.
Look at how the water clings to the pipe wall in the boundary layer.
The sensor is placed precisely within the atmospheric boundary layer to capture accurate wind data.
I feel like I am stuck in a boundary layer between my professional and personal life.
