A phenomenon known as laminar flow occurs when air move in parallel layers without mixing. It contrasts with turbulent flow, in which molecules move over a region in a variety of ways and continually mix.
Laminar air flow, in contrast to HVAC systems, offers a means of preserving the pure quality of air inside a place and also avoids air mixing, which can lead to contamination. Clean areas such as surgery rooms and labs frequently employ laminar flow HVAC systems.
Now let’s get a clear understanding on these two types of flows.
Turbulent Airflow
If you take a room and attach a supply diffuser and a return grille on the ceiling, you can witness the air turbulence in the room.
Here, the air moves in an unpredictable way, which is dictated by the differences in the temperature and the pressure. The air molecules constantly collide with each other and tend to create air contamination. The particles are then transported across the room before leaving the room from the return grille.
Now let’s understand the concept of laminar air flow.
Laminar Airflow
In a room with attaches supply diffusers and a return grille on the floor, you can see how the air flow is consistent and equivalent with no turbulence.
In the case of laminar airflow situation, the air move quite predictably and in a parallel layers and similar manner from the supply diffusers attached to the ceiling of a room. As the return grilles are located on the floor, the air is forcibly pushed down towards the return window. The air does not have to move back through the clean air to the returns, as it happens in the turbulent air flow case.
This prevents air contamination as many unwanted particles are eliminated directly through the returns outside the room in a straight line.
Laminar Flow Cabinets and its application
Although the aforementioned examples presume that the area is a room with ducts supplying air, the area can even be a desktop device known as a Laminar Flow Hood or Laminar Flow Cabinet that is utilized in a laboratory.
Under that instance, the air is forced over the items under the hood in a smooth, laminar air flow after passing through a HEPA filter. There are several sizes and air flow options available for the hoods. The objective is always the same, regardless of the application: to keep the air completely clean, by allowing circulation in separate, parallel layers.
