air flow turbulence

The organization of air distribution is one of the key aspects of creating a comfortable and healthy indoor climate. The effectiveness of this process affects not only temperature and humidity, but also overall air quality, which directly impacts people's well-being. To ensure optimal air distribution, a variety of ventilation devices are used, including grilles and diffusers, which differ in design and technical characteristics. Recently, louvered linear diffusers have gained considerable popularity, combining high functionality with modern design.

This article investigates the aerodynamic behavior and efficiency of swirled air jets used in modern ventilation systems. The influence of rotational motion on turbulence intensity, mixing efficiency, and air distribution uniformity is assessed. Results confirm that swirled jets enhance air mixing and reduce axial velocity and temperature gradients more effectively than traditional non-swirled jets. Key dimensionless parameters, such as velocity and temperature attenuation coefficients, are introduced to simplify calculations.

The article investigates the improvement of air distribution efficiency in a room when using a linear diffuser as an air distribution device. Linear diffusers allow to provide comfortable conditions in the room.
