What Does DBL Stand For?

DBL stands for Diffusive Boundary Layer

DBL, or Diffusive Boundary Layer, refers to the region in fluid dynamics where the concentration gradient of a solute or temperature decreases rapidly alongside a solid boundary. This layer plays a crucial role in mass and heat transfer processes, influencing the interaction between the fluid and the surface it flows over. The characteristics of the DBL are essential for understanding diffusion mechanisms in various applications, including environmental science, chemical engineering, and biophysics.
