2023
Source: David Guo, College of Engineering, Technology, and Aeronautics (CETA), Southern New Hampshire University (SNHU), Manchester, New Hampshire A Pitot-static tube is widely used for measuring unknown speeds in air flow, for example, it is used to measure airplane airspeed. By Bernoulli's principle, airspeed is directly related to variations in pressure. Therefore, the Pitot-static tube senses the stagnation pressure and static pressure. It is connected to a manometer or pressure transducer...

The rectification of ion transport pathways is an effective method to generate one-directional ion-dragged electrohydrodynamic flows. By setting an ion-exchange membrane in a flow channel, an electrically polarized condition is generated and causes a liquid flow to be driven when an electric field is externally applied.
FAQs
The system links air movement with pressure, temperature, and distribution requirements rather than treating airflow as a fixed setting. Fans or blowers provide movement, while ducts, vents, and dampers guide and adjust volume or direction. This coordinated response helps maintain desired conditions when measured environmental variables change, supporting ventilation, thermal comfort, and contamination management.
Sensors provide measurements that guide adjustments to the airflow system. They can monitor conditions such as pressure, temperature, or pollutant concentration, allowing fans, blowers, or dampers to respond to changing requirements. This feedback-based approach connects environmental conditions with system operation, helping maintain indoor air quality and supporting more controlled conditions in engineered spaces.
Each component contributes a different function to air handling. Ducts and vents establish pathways and distribution, dampers adjust airflow volume or direction, and filters support air-quality management. Their combined arrangement determines how effectively air reaches intended areas and how well the system supports ventilation, contamination control, and desired environmental conditions.
Performance depends on the relationship among airflow volume, pressure, temperature, direction, and pollutant concentration. A change in one measured condition can alter the required response from fans, blowers, dampers, or sensors. Considering these variables together is important because the same system must often balance air quality, thermal comfort, contamination management, and energy efficiency.
A practical workflow begins by identifying the desired environmental conditions and the variables that need monitoring. Designers then coordinate fans or blowers with ducts, vents, dampers, filters, and sensors to distribute and adjust air. The system can subsequently respond to measured pressure, temperature, or pollutant concentration, with performance judged by ventilation, comfort, contamination control, and energy goals.
The approach applies across buildings, laboratories, industrial facilities, and climate-controlled spaces. Depending on the setting, it can support ventilation, indoor air quality, thermal comfort, contamination management, or energy efficiency. In environmental research, the same principles help examine pollutant transport and inform sustainable environmental management by relating air movement to changing conditions.
