mikroströmning
Mikroströmning refers to fluid flow at the microscale, typically within channels or devices with characteristic dimensions ranging from microns to a few hundred microns. This regime of fluid dynamics exhibits unique behaviors compared to macroscopic flows due to the increased significance of surface forces, viscous effects, and diffusion. At the microscale, the Reynolds number, which compares inertial forces to viscous forces, is generally low, leading to laminar flow regimes where fluid layers slide past each other smoothly without turbulence.
The behavior of fluids in microchannels is heavily influenced by surface-to-volume ratios. Surface tension, surface charge,
Microströmning is fundamental to the field of microfluidics, which involves the manipulation of small fluid volumes
