What is Laminar Air Flow & its Uses?
What is laminar air flow?
Laminar air flow controls air movement in a straight and smooth path. It creates a clean and sterile environment by reducing turbulence. This system prevents contaminated air from mixing. Laminar flow happens when fluid moves in smooth and parallel layers with little or no mixing. Each layer flows steadily passed the others without swirls or turbulence. Additionally, the fluid stays in order at low speeds. In this case, particles stay near solid surfaces and move in straight and parallel lines. Fluid can flow into ways, that is laminar flow or turbulent flow. Laminar flow occurs at lower speeds. When viscosity and channel size keep the movement smooth. On the other hand, turbulent flow creates chaotic movement with swirls and mixing. Laminar air flow hood is used in labs, hospitals, and manufacturing units. Note that air moves in layers at a constant speed. It pushes away particles like dust and bacteria. Laminar flow can be horizontal or vertical. It often uses HEPA filters to remove 99.97% particles. This makes them ideal for medicines, experiments, or electronics.
