õhuvoo
Õhuvoo is the movement of air relative to a region, typically described as a vector field of air velocity. In the atmosphere it manifests as wind, while in buildings and other enclosed spaces it results from fans, vents, and temperature or pressure differences. It is governed by fluid dynamics and can be analyzed in terms of velocity, volume flow rate, and pressure variations.
The main drivers of õhuvoo are pressure differences, buoyancy due to temperature and density contrasts, and
Õhuvoo can be broadly categorized as laminar, where air particles move smooth periods in parallel layers, and
Applications of understanding õhuvoo span meteorology, ventilation and HVAC design, indoor air quality, and aerodynamic testing.
Measurement methods include anemometers and vane meters for velocity, pitot tubes for dynamic pressure, and smoke
