Virtaushäiriöillä
Virtaushäiriöillä refers to flow disturbances or flow instabilities in fluid dynamics. These phenomena occur when the smooth, predictable movement of a fluid is disrupted. The transition from laminar flow, where fluid particles move in parallel layers, to turbulent flow, characterized by chaotic eddies and mixing, is a common example of a virtaushäiriö.
These disturbances can arise from various factors, including increased flow velocity, obstacles in the flow path,
